Description

Technical Field

[0001] This application relates to the field of power supply technology for integrated braking electronic control systems, and in particular to a power supply regulation method and related device. Background Technology

[0002] With the development of intelligent and connected vehicles, more and more vehicles are being equipped with Integrated Brake Control (IBC) systems. This necessitates the establishment of IBC performance test benches to troubleshoot IBC issues and test and approve its performance. Therefore, the IBC needs to operate at an accurate and stable operating voltage, provided by a programmable power supply. However, current technology involves offline adjustment of the programmable power supply's output voltage based on empirical values. This method cannot guarantee the stability of the programmable power supply's output voltage, resulting in inaccurate simulated operating conditions. Therefore, a method is needed to dynamically adjust the operating voltage across the IBC and the on / off state of the power supply circuit. Summary of the Invention

[0003] To address the aforementioned issues, embodiments of this application provide a power supply regulation method and related apparatus, which can provide a method for dynamically regulating the operating voltage across the IBC terminals and the on / off state of the power supply circuit.

[0004] According to one aspect of an embodiment of this application, a power supply regulation method is proposed, applied to a power supply regulation system. The power supply regulation system includes an integrated braking electronic control system, a test controller, a programmable power supply, a relay unit, and a hub. The integrated braking electronic control system is used to receive command signals sent by a vehicle. The method is applied to the test controller, and the method includes: The system receives a conversion signal sent by the integrated brake electronic control system, the conversion signal being obtained by the integrated brake electronic control system through signal conversion of the command signal; The operating mode of the power supply regulation system is determined based on the conversion signal; When the operating mode is normal power supply mode, a first control signal for the programmable power supply is determined according to the conversion signal, and the first control signal is sent to the programmable power supply so that the programmable power supply supplies power to the integrated braking electronic control system according to the first control signal; When the operating mode is the voltage regulation mode, a second control signal for the programmable power supply is determined according to the conversion signal, and the second control signal is sent to the programmable power supply so that the programmable power supply provides regulated power to the integrated braking electronic control system according to the second control signal; When the operating mode is the function switching mode, a third control signal for the relay unit is determined according to the conversion signal, and the third control signal is sent to the relay unit so that the relay unit switches states according to the third control signal to control the on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub. The normal power supply mode is used to indicate that the vehicle is in a normal driving state and is not braking, while the voltage regulation mode is used to indicate that the vehicle is in a braking state.

[0005] In the above scheme, determining the operating mode of the power supply regulation system based on the conversion signal includes: If the conversion signal is the first conversion signal, then the working mode of the power supply regulation system is determined to be the normal power supply mode. The first conversion signal is used to characterize that the vehicle has not started the active boost and active depressurization functions. If the conversion signal is the second conversion signal, then the working mode of the power supply regulation system is determined to be the voltage regulation mode. The second conversion signal is used to indicate that the vehicle has started the active boost and active depressurization functions. If the conversion signal is a third conversion signal, then the operating mode of the power supply regulation system is determined to be the function switching mode, and the third conversion signal is used to indicate that the vehicle is in a preset state; When the vehicle is in the preset state, the power supply regulation system achieves power supply self-regulation by controlling the on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub.

[0006] In the above scheme, the test controller includes a power supply voltage control module and a voltage setpoint module. Determining the first control signal for the programmable power supply based on the conversion signal includes: When the conversion signal is the first conversion signal, the first digital signal of the power supply voltage control module is determined according to the first conversion signal, and the first digital signal is sent to the voltage setpoint module; The voltage setpoint module generates the first control signal based on the received first digital signal, so that the programmable power supply outputs a first target voltage to the integrated braking electronic control system according to the first control signal.

[0007] In the above scheme, the test controller further includes a working voltage acquisition module and a PI controller module, and the step of determining the second control signal for the programmable power supply based on the conversion signal includes: When the conversion signal is the second conversion signal, the second digital signal of the power supply voltage control module is determined according to the second conversion signal, and the second digital signal is sent to the voltage setpoint module; Receive the actual operating voltage of the integrated braking electronic control system acquired by the operating voltage acquisition module; If the actual operating voltage is inconsistent with the second target operating voltage corresponding to the second digital signal, the PI controller module is controlled to perform proportional and integral control based on the actual operating voltage and the second target operating voltage, and the signal obtained after proportional and integral control is used as the second control signal.

[0008] In the above scheme, the relay unit includes a first relay and a second relay disposed between the hub and the programmable power supply, and a third relay and a fourth relay disposed between the hub and the integrated brake electronic control system. Determining the third control signal for the relay unit based on the conversion signal includes: When the conversion signal is the third conversion signal, the value of the third conversion signal is determined; The states of the first relay, the second relay, the third relay, and the fourth relay are determined based on the value of the third conversion signal, so as to determine the on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub; The third control signal is generated based on the determined on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub.

[0009] In the above scheme, determining the states of the first relay, the second relay, the third relay, and the fourth relay based on the value of the third conversion signal includes: If the value of the third conversion signal is the first value, then the state of the first relay is determined to be low, the state of the second relay is low, the state of the third relay is low, and the state of the fourth relay is low, so that the programmable power supply, the integrated braking electronic control system, the test controller, and the hub are interconnected. If the value of the third conversion signal is the second value, then the state of the first relay is determined to be low, the state of the second relay is low, the state of the third relay is high, and the state of the fourth relay is low, so that the integrated braking electronic control system is in an open circuit state. If the value of the third conversion signal is a third value, then the state of the first relay is determined to be low, the state of the second relay is low, the state of the third relay is low, and the state of the fourth relay is high, so that the test controller is in an open circuit state. If the value of the third conversion signal is the fourth value, then the state of the first relay is determined to be low, the state of the second relay is low, the state of the third relay is high, and the state of the fourth relay is high, so that the programmable power supply, the integrated braking electronic control system, and the hub are in a power supply disconnection state. If the value of the third conversion signal is the fifth value, then the state of the first relay is determined to be high, the state of the second relay is high, the state of the third relay is low, and the state of the fourth relay is low, so that the programmable power supply, the integrated braking electronic control system, and the hub are in a reverse connection state.

[0010] In the above scheme, a capacitor is connected in parallel across the two ends of the programmable power supply, and the capacitance value of the capacitor is related to the conversion signal.

[0011] According to one aspect of the embodiments of this application, a power supply regulating device is provided, applied to a power supply regulating system. The power supply regulating system includes an integrated brake electronic control system, a test controller, a programmable power supply, a relay unit, and a hub. The integrated brake electronic control system is used to receive command signals sent by a vehicle. The method is applied to the test controller. The device includes: The receiving unit is used to receive a conversion signal sent by the integrated brake electronic control system, wherein the conversion signal is obtained by the integrated brake electronic control system through signal conversion of the command signal; The first determining unit is used to determine the operating mode of the power supply regulation system based on the conversion signal; The second determining unit is configured to determine a first control signal for the programmable power supply based on the conversion signal when the operating mode is normal power supply mode, and send the first control signal to the programmable power supply so that the programmable power supply supplies power to the integrated braking electronic control system according to the first control signal. The third determining unit is configured to, when the operating mode is the voltage regulation mode, determine a second control signal for the programmable power supply based on the conversion signal, and send the second control signal to the programmable power supply so that the programmable power supply provides regulated power to the integrated braking electronic control system according to the second control signal; The fourth determining unit is configured to, when the operating mode is a function switching mode, determine a third control signal for the relay unit based on the conversion signal, and send the third control signal to the relay unit so that the relay unit switches states according to the third control signal to control the on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub. The normal power supply mode is used to indicate that the vehicle is in a normal driving state and is not braking, while the voltage regulation mode is used to indicate that the vehicle is in a braking state.

[0012] The beneficial effects of this application are as follows: The power supply regulation method of this application is applied in a power supply regulation system. The vehicle braking system includes an integrated braking electronic control system, a test controller, a programmable power supply, a relay unit, and a hub. The test controller can control the relay unit to switch states, thereby controlling the on / off states between the integrated braking electronic control system, the test controller, the programmable power supply, and the hub, thereby performing power supply regulation.

[0013] Furthermore, the vehicle can send command signals to the integrated braking electronic control system. This system can convert these command signals into a conversion signal, which determines the operating mode of the power supply regulation system. There are three operating modes: normal power supply mode, voltage regulation mode, and function switching mode. Normal power supply mode is the power supply mode when the vehicle is in normal driving condition, while voltage regulation mode is the power supply mode when the vehicle is braking, enabling constant voltage power supply based on the vehicle's different states.

[0014] Furthermore, the operating mode can also be a function switching mode. For example, under ultra-high voltage conditions in the vehicle, it can control the on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub to protect the device and improve safety.

[0015] In summary, this application provides a method for dynamically adjusting the operating voltage and power supply circuit on / off at both ends of the IBC while improving security. Attached Figure Description

[0024] The following describes the vehicle braking system proposed in the embodiments of this application: Please see Figure 2 , Figure 2This is a system architecture diagram of the power supply regulation system, which includes an integrated brake control (IBC) test controller, a programmable power supply, relay units, and a hub. The test controller includes a power supply voltage control software module and a power supply voltage control hardware module. The power supply voltage control software module includes a power supply voltage control module, a voltage setpoint module, a PI controller module, a relay control module, and a working voltage acquisition module. The power supply voltage control hardware module includes DA signal conversion interfaces, DO signal conversion interfaces, AD signal conversion interfaces, and CAN signal conversion interfaces. These conversion interfaces are used to generate conversion signals, first control signals, second control signals, and third control signals. The relay unit includes relay 1 (first relay), relay 2 (second relay), relay 3 (third relay), and relay 4 (fourth relay). Relays 1 and 2 have normally-on and normally-off terminals. A capacitor C1 is connected in parallel across the positive and negative terminals of the programmable power supply to achieve voltage regulation. The positive terminal of the programmable power supply is connected to a fuse, and the other end of the fuse is connected to the normally-on terminal of relay 1. When the current in the power supply circuit exceeds the fuse's melting threshold, the fuse blows to protect the power supply and other electronic components. The middle terminal of relay 1 is connected to the positive terminal of the hub, and the normally closed terminal of relay 1 is connected to the negative terminal of the programmable power supply. The negative terminal of the programmable power supply is connected to the normally open terminal of relay 2. The middle terminal of relay 2 is connected to the negative terminal of the hub, and the normally closed terminal of relay 2 is connected to the other end of the fuse. The positive terminal 1 of the hub is connected to the positive terminal of the IBC motor power supply, and the positive terminal 2 of the hub is connected to the positive terminal of the IBC controller power supply; the negative terminal 1 of the hub is connected to relay 3, and relay 3 is connected to the negative terminal of the IBC motor power supply; the negative terminal 2 of the hub is connected to relay 4, and the other end of relay 4 is connected to the negative terminal of the IBC controller power supply.

[0025] For relays 1 and 2, the test controller controls each relay coil to connect its intermediate terminal to its normally open terminal when both ends are at a low level (e.g., 0V) via the DO (digital output) signal conversion interface; and connects its intermediate terminal to its normally closed terminal when both ends are at a high level (e.g., 12V).

[0026] The positive terminal of the hub connects to the positive terminals 1 and 2 inside the hub, and the negative terminal connects to the negative terminals 1 and 2 inside the hub.

[0027] For relays 3 and 4, the test controller controls each relay coil to be connected when the two ends are at a low level (e.g., 0V) and disconnected when the two ends are at a high level (e.g., 12V) via the DO (digital output) signal conversion interface.

[0028] The following provides a detailed description of the specific implementation methods of the embodiments of this application: Please see Figure 3 , Figure 3 This is a flowchart illustrating the power supply adjustment method provided in the embodiments of this application. The power supply adjustment method can be implemented by server 110 and / or terminal 140. Figure 3 The power supply regulation methods shown include: Step 310: Receive a conversion signal sent by the integrated brake electronic control system, wherein the conversion signal is obtained by the integrated brake electronic control system through signal conversion of the command signal; Step 320: Determine the operating mode of the power supply regulation system based on the conversion signal; Step 330: When the working mode is normal power supply mode, determine a first control signal for the programmable power supply according to the conversion signal, and send the first control signal to the programmable power supply so that the programmable power supply supplies power to the integrated braking electronic control system according to the first control signal; Step 340: When the working mode is the voltage regulation function mode, determine the second control signal for the programmable power supply according to the conversion signal, and send the second control signal to the programmable power supply so that the programmable power supply provides regulated power to the integrated braking electronic control system according to the second control signal; Step 350: When the working mode is the function switching mode, a third control signal for the relay unit is determined according to the conversion signal, and the third control signal is sent to the relay unit so that the relay unit switches states according to the third control signal to control the on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub. The normal power supply mode is used to indicate that the vehicle is in a normal driving state and is not braking, while the voltage regulation mode is used to indicate that the vehicle is in a braking state.

[0029] The complete embodiment of this application will be explained in detail below with reference to steps 310-350: In step 310, the vehicle can send command signals to the integrated brake electronic control system. These command signals can represent vehicle speed, active boost and active depressurization status, or other status information, as well as the control commands required by the vehicle, such as commands requiring the programmable power supply to provide the voltage needed for the IBC. The integrated brake electronic control system can convert the command signals into converted signals via the aforementioned CAN signal conversion interface and send them to the power supply voltage control module in the test controller.

[0030] In step 320, the operating mode of the power supply regulation system can be determined by converting the signal.

[0031] In some embodiments, determining the operating mode of the power supply regulation system based on the conversion signal includes: If the conversion signal is the first conversion signal, then the working mode of the power supply regulation system is determined to be the normal power supply mode. The first conversion signal is used to characterize that the vehicle has not started the active boost and active depressurization functions. If the conversion signal is the second conversion signal, then the working mode of the power supply regulation system is determined to be the voltage regulation mode. The second conversion signal is used to indicate that the vehicle has started the active boost and active depressurization functions. If the conversion signal is a third conversion signal, then the operating mode of the power supply regulation system is determined to be the function switching mode, and the third conversion signal is used to indicate that the vehicle is in a preset state; When the vehicle is in the preset state, the power supply regulation system achieves power supply self-regulation by controlling the on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub.

[0032] In step 330, when the operating mode is normal power supply mode, the first conversion signal corresponds to the voltage default function adjustment method: The test controller includes a power supply voltage control module and a voltage setpoint module. Determining the first control signal for the programmable power supply based on the conversion signal includes: When the conversion signal is the first conversion signal, the first digital signal of the power supply voltage control module is determined according to the first conversion signal, and the first digital signal is sent to the voltage setpoint module; The voltage setpoint module generates the first control signal based on the received first digital signal, so that the programmable power supply outputs a first target voltage to the integrated braking electronic control system according to the first control signal.

[0033] The CAN signal conversion interface receives the active boost and active depressurization function status (determined from the conversion signal) sent by the IBC in real time and sends it to the power supply voltage control module. When neither the active boost nor active depressurization function is activated (i.e., both active boost and active depressurization function statuses are "0"), the power supply voltage control module sends a power supply voltage control mode command with a value of "0" to the voltage setpoint module. The voltage setpoint module sends a first target operating voltage (such as 10, 12, 16V, etc.) to the DA signal conversion interface. The DA signal conversion interface converts the target operating voltage into an analog voltage signal (first control signal) and sends it to the programmable power supply. The programmable power supply outputs the first target operating voltage to power the IBC, where "0" is the first digital signal described in this application.

[0034] In step 340, when the operating mode is voltage regulation mode, the second conversion signal corresponds to the voltage regulation method: The test controller further includes a working voltage acquisition module and a PI controller module. The step of determining a second control signal for the programmable power supply based on the conversion signal includes: When the conversion signal is the second conversion signal, the second digital signal of the power supply voltage control module is determined according to the second conversion signal, and the second digital signal is sent to the voltage setpoint module; Receive the actual operating voltage of the integrated braking electronic control system acquired by the operating voltage acquisition module; If the actual operating voltage is inconsistent with the second target operating voltage corresponding to the second digital signal, the PI controller module is controlled to perform proportional and integral control based on the actual operating voltage and the second target operating voltage, and the signal obtained after proportional and integral control is used as the second control signal.

[0035] The CAN signal conversion interface receives the active boost and active depressurization function status sent by the IBC in real time and sends it to the power supply voltage control module. When the active boost or active depressurization function is activated (i.e., the active boost or active depressurization function status is "1"), "1" is the second digital signal described in this application. The power supply voltage control mode module sends a power supply voltage control mode command with a value of "1" to the voltage setpoint module. The voltage setpoint module sends the second target working voltage (such as 10, 12, 16V, etc.) and calculates the difference between it and the actual working voltage sent by the working voltage acquisition module. This difference is proportionally and integrally controlled by the PI controller module, and the control quantity power supply voltage is output to the DA signal conversion interface. The DA signal conversion interface converts the power supply voltage into an analog voltage signal (second control signal) and sends it to the programmable power supply. The programmable power supply outputs this power supply voltage to power the IBC. The working voltage acquisition module acquires the current working voltage value of the positive terminal 1 in the hub through the AD signal conversion interface. After filtering, it generates the actual working voltage to participate in the calculation of the difference, thereby realizing closed-loop control.

[0036] In step 350, when the operating mode is the function switching mode, the following can be achieved: Figure 4 The various functions shown can be switched automatically, such as the IBC power supply normal function can be switched to the motor disconnect function and the controller disconnect function; the IBC power supply disconnect function can be switched to the motor disconnect function, the controller disconnect function, and the reverse connection function; the motor disconnect function can be switched to the IBC power supply normal function and the IBC power supply disconnect function; the controller disconnect function can be switched to the IBC power supply normal function and the IBC power supply disconnect function; and the reverse connection function can be switched to the IBC power supply disconnect function.

[0037] In some embodiments, determining a third control signal for the relay unit based on the conversion signal includes: When the conversion signal is the third conversion signal, the value of the third conversion signal is determined; The states of the first relay, the second relay, the third relay, and the fourth relay are determined based on the value of the third conversion signal, so as to determine the on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub; The third control signal is generated based on the determined on / off state between the integrated braking electronic control system and / or the test controller and / or the programmable power supply and / or the hub.

[0038] Determining the states of the first relay, the second relay, the third relay, and the fourth relay based on the value of the third conversion signal includes: If the value of the third conversion signal is the first value, then the state of the first relay is determined to be low, the state of the second relay is low, the state of the third relay is low, and the state of the fourth relay is low, so that the programmable power supply, the integrated braking electronic control system, the test controller, and the hub are interconnected. If the value of the third conversion signal is the second value, then the state of the first relay is determined to be low, the state of the second relay is low, the state of the third relay is high, and the state of the fourth relay is low, so that the integrated braking electronic control system is in an open circuit state. If the value of the third conversion signal is a third value, then the state of the first relay is determined to be low, the state of the second relay is low, the state of the third relay is low, and the state of the fourth relay is high, so that the test controller is in an open circuit state. If the value of the third conversion signal is the fourth value, then the state of the first relay is determined to be low, the state of the second relay is low, the state of the third relay is high, and the state of the fourth relay is high, so that the programmable power supply, the integrated braking electronic control system, and the hub are in a power supply disconnection state. If the value of the third conversion signal is the fifth value, then the state of the first relay is determined to be high, the state of the second relay is high, the state of the third relay is low, and the state of the fourth relay is low, so that the programmable power supply, the integrated braking electronic control system, and the hub are in a reverse connection state.

[0039] Specifically, the first value corresponds to the adjustment method for normal IBC power supply function: The power supply voltage control module sends a relay control mode command with a value of "11" (first value) to the relay control module. The relay control module sets the voltage of relay 1, relay 2, relay 3, and relay 4 to low level, and sends the above signals to the DO signal conversion interface. The DO signal conversion interface performs corresponding voltage control on relays 1, 2, 3, and 4.

[0040] The second value corresponds to the adjustment method of the IBC circuit breaker function. The power supply voltage control module sends a relay control mode command with a value of "12" (second value) to the relay control module. The relay control module sets the voltage of relay 1 to low level, the voltage of relay 2 to low level, the voltage of relay 3 to high level, and the voltage of relay 4 to low level, and sends the above signals to the DO signal conversion interface. The DO signal conversion interface performs corresponding voltage control on relays 1, 2, 3, and 4.

[0041] Based on the active boost and active depressurization function status sent by the IBC, the power supply voltage control mode module sends a power supply voltage control mode command with a value of "0" (first digital signal) or "1" (second digital signal) to the voltage setpoint module and the DA signal conversion interface. Since relays 3 and 4 are respectively in the motor power supply negative circuit and the controller power supply negative circuit, and the AD signal conversion interface collects the working voltage value of the motor power supply positive terminal, the motor circuit breaking function can perform PI control of the power supply voltage in the voltage regulation function.

[0042] The voltage setpoint module sends the target operating voltage (such as 10, 12, 16V, etc.) to the DA signal conversion interface. The DA signal conversion interface converts the target operating voltage into an analog voltage signal and sends it to the programmable power supply. The programmable power supply outputs the target operating voltage to power the IBC.

[0043] The third value corresponds to the controller's circuit breaker function adjustment method: The power supply voltage control module sends a relay control mode command with a value of "13" (the third value) to the relay control module. The relay control module sets the voltage of relay 1 to low level, the voltage of relay 2 to low level, the voltage of relay 3 to low level, and the voltage of relay 4 to high level. The controller's circuit breaker function can also perform PI control of the power supply voltage in the voltage regulation function.

[0044] The fourth value corresponds to the IBC power supply disconnection function adjustment method: The power supply voltage control module sends a relay control mode command with a value of "14" (fourth value) to the relay control module. The relay control module sets the voltage of relay 1 to low level, the voltage of relay 2 to low level, the voltage of relay 3 to high level, and the voltage of relay 4 to high level. The controller's circuit breaker function can also perform PI control of the power supply voltage in the voltage regulation function.

[0045] The fifth value corresponds to the reverse connection function adjustment method: The power supply voltage control module sends a relay control mode command with a value of "15" (the fifth value) to the relay control module. The relay control module sets the voltage of relay 1 to high level, relay 2 to high level, relay 3 to low level, and relay 4 to low level, and sends the above signals to the DO signal conversion interface. The DO signal conversion interface performs corresponding voltage control on relays 1, 2, 3, and 4. If switching from normal IBC power supply function to reverse connection function or from reverse connection function to normal IBC power supply function, the voltage level change of relay 1 can be before or after the voltage level change of relay 2 without causing a short circuit in the programmable power supply.

[0046] The prerequisite for the power supply voltage control mode module to send a relay control mode command with a value of "15" is that the CAN signal conversion interface receives a vehicle speed value of 0 from the IBC and the previous function is the IBC power supply disconnection function.

[0047] The power supply voltage control mode module sends a power supply voltage control mode command with a value of "0" to the voltage setpoint module. The voltage setpoint module sends the target operating voltage (such as 10, 12, 16V, etc.) to the DA signal conversion interface. The DA signal conversion interface converts the target operating voltage into an analog voltage signal and sends it to the programmable power supply. The programmable power supply outputs the target operating voltage to power the IBC in reverse polarity.

[0048] In some embodiments, a capacitor C1 is connected in parallel across the positive and negative terminals of the programmable power supply. This provides a certain degree of voltage regulation under voltage regulation mode, reducing the amplitude of voltage fluctuations across the IBC. Adjusting the basic value of the IBC operating voltage is primarily achieved by the aforementioned PI control circuit. The capacitor C1 connected in parallel across the positive and negative terminals of the programmable power supply can provide voltage regulation in both regulation mode and normal power supply mode. The capacitance value of capacitor C1... The calculation method is as follows:

[0049] in, and This refers to the start and end times when the active boost or active depressurization function is in state "1" (first digital signal) within a single time period. This represents the number of time periods when the active boost or active depressurization function is in state "1" (second digital signal). This is the current value of the programmable power supply circuit when the active boost or active deboost function is in state "1". This is the upper limit of the allowable operating voltage across the IBC terminals (calibrable). This is the lower limit of the allowable operating voltage across the IBC terminals (calibrable).

[0050] In summary, this application decomposes the power supply method into voltage function (corresponding to normal power supply mode and voltage regulation mode) and on / off function (corresponding to function switching mode). The voltage function is further decomposed into two types: voltage default function (corresponding to the normal power supply mode) and voltage regulation function (corresponding to the voltage regulation mode). The on / off function is further decomposed into five types: IBC power supply normal function, IBC power supply disconnection function, motor disconnection function, controller disconnection function, and reverse connection function. By automatically controlling the on / off of the relay unit, the automatic switching of different functions is achieved.

[0051] This application, through the arrangement of multiple relays in the relay unit, ensures that the programmable power supply does not short-circuit when switching between the normal and reverse connection functions of the IBC power supply.

[0052] This application uses the active boost and active deboost functions as indicators to distinguish between the voltage default function and the voltage regulation function. For the voltage default function, the voltage fluctuation is reduced only by capacitors. For the voltage regulation function, the working voltage across the IBC is monitored in real time, and the output voltage of the programmable power supply is automatically adjusted by the PI controller. When high-power-consuming functions such as active deboost and active boost are activated, in addition to reducing the voltage fluctuation by capacitors, the basic voltage value across the IBC is also appropriately increased to keep the working voltage across the IBC stable.
