[0027] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0028] Due to the increasing requirements for the power range of high-power loads, the load-carrying capacity limitation of high-power output circuits has gradually become prominent. The long-term operation of high-power loads will cause some components of the high-power output circuit to overheat, and even lead to component damage, affecting the reliability and working efficiency of the high-power output circuit.
[0029] To solve the above problems, embodiments of the present disclosure provide a high-power load processing system and method. A high-power load processing system is composed of multiple groups of high-power output circuits, sharing and multiplexing the output capabilities of multiple groups of high-power output circuits, solving the problems of poor reliability and low efficiency when high-power output circuits continuously drive high-power loads, and realizing high-efficiency, reliable, and flexible high-power load carrying on the basis of effectively controlling the implementation cost.
[0030] An exemplary embodiment of the present disclosure provides a high-power load processing system, the structure of which is as Figure 1 shown, including: a controller 101 and at least two groups of high-power output circuits 102.
[0031] Wherein, the high-power output circuit 102 includes a diode 1021, a dynamic load 1022, and a control switch 1023. The diode 1021 is connected to a power supply (VDD) and is in series with the control switch 1023. The dynamic load 1022 is connected in parallel to the first connection point 1024 and the second connection point 1025 on both sides of the diode 1021.
[0032] According to an exemplary embodiment, one end of the control switch 1023 is connected to the negative electrode of the diode 1021, and the other end is grounded. When the control switch 1023 is turned on, the corresponding high-power output circuit is turned on to drive the load.
[0033] The dynamic load 1022 can be configured according to actual application requirements as follows: 1. Load size; 2. Connection or disconnection of the dynamic load to the first connection point 1024 and / or the second connection point 1025.
[0034] There is an electrical connection between the first connection points 1024 of the high-power output circuits 102 in each group, and there is an intermittent electrical connection between the second connection points 1025 of the high-power output circuits 102 in each group. The intermittent electrical connection between the second connection points 1025 indicates that for any two second connection points 1025, there is an electrical connection under certain conditions and it is disconnected under other conditions. For the connection or disconnection of this intermittent electrical connection, it can be achieved by mechanical (such as physical switches, relays, etc.), electronic (such as transistor switches, analog switches, etc.), software (such as program control, communication control, etc.) and other technical means.
[0035] The controller 101 is connected to the control terminals of the control switches 1023 of the high-power output circuits 102 in each group, and sends control signals to the control switches 1023 to control the conduction or cutoff of the control switches 1023.
[0036] Further, the control switch 1023 includes a MOSFET switch, the control terminal is the gate of the MOSFET, and the second connection point 1025 is connected to the drain of the control switch 1023.
[0037] According to an exemplary embodiment, the control switch 1023 includes an insulated gate bipolar transistor (IGBT) switch, and the control terminal is the gate of the IGBT. The second connection point 1025 can be connected to the collector of the control switch 1023.
[0038] An exemplary embodiment of the present disclosure further provides a high-power load processing system. The intermittent electrical connection between the second connection points 1025 of the high-power output circuits 102 in each group is disconnected, that is, there is no electrical connection between the second connection points 1025 of the high-power output circuits 102 in each group. In this case, the high-power output circuits in each group work independently to drive the dynamic load connected between the first connection point and the second connection point of the high-power output circuit.
[0039] The controller can send a control signal to the control switch of the high-power output circuit to make the control switch conduct. The switch can be controlled by signals such as PWM, and can also be controlled by soft-switching technology, or controlled by feedback control. According to an exemplary embodiment, the conduction or cutoff of the control switch can also be achieved by a mechanical switch.
[0040] Further, the conduction time can also be controlled to cutoff after conducting for a period of time; the operation process of conduction-cutoff can also be repeated periodically.
[0041] An exemplary embodiment of the present disclosure further provides a high-power load processing system. There is an intermittent electrical connection between the second connection points 1025 of some or all of the high-power output circuits 102, that is, there is an electrical connection between the second connection points 1025 of some or all of the high-power output circuits 102. At this time, the control switches of some or all of the high-power output circuits are connected in parallel.
[0042] For ease of description, in this embodiment, the multiplexing circuit set is temporarily used to represent some or all of the high-power output circuits 102.
[0043] One or more dynamic loads 1022 to be driven are connected in parallel between the first connection point 1024 and the second connection point 1025.
[0044] During the driving of one or more dynamic loads 1022, at least one control switch 1023 in the multiplexing circuit set is in the on state.
[0045] According to an exemplary embodiment, at the same moment, the controller 101 controls one control switch 1023 in the multiplexing circuit set to be turned on. During the driving of the dynamic load 1022, the controller 101 controls multiple different control switches 1023 in the multiplexing circuit set to be turned on at different times, so as to drive the dynamic load 1022 through different high-power output circuits 102, and avoid problems such as overheating and even device failure caused by continuous use of the same high-power output circuit 102.
[0046] According to an exemplary embodiment, for MOSFET switches, at this time, an electrical connection is established between the drains of the MOSFET switches of each high-power output circuit.
[0047] An exemplary embodiment of the present disclosure further provides a high-power load processing method, which is applicable to the high-power load processing system provided by the embodiment of the present disclosure. Using this method, it is possible to turn on multiple groups of high-power output circuits at different times, and effectively control the heat generation of the high-power output circuits when driving high-power loads. The process of driving a high-power load using this method is as Figure 2 shown, including: Step 201, obtain a control strategy.
[0048] In this step, the controller obtains a control strategy, and the control strategy includes the turning on and / or off of at least one control switch.
[0049] According to an exemplary embodiment, the control strategy at least further includes any one or any combination of the following information: The turn-on operation time of each control switch, the turn-on duration of each control switch, the turn-off operation time of each control switch, and the turn-off duration of each control switch.
[0050] According to an exemplary embodiment, the control strategy may further indicate a working mode, such as a working mode in which each group of high-power output circuits works independently, or some / all of the high-power output circuits By obtaining the control strategy, information related to the on / off operation of the control switch can be obtained. The controller can then control multiple groups of high-power output circuits according to this operation-related information.
[0051] Step 202: Control the output of the high-power output circuit according to the control strategy.
[0052] In this step, for the cases where each group of high-power output circuits works independently and some / all of the high-power output circuits work cooperatively, control is performed separately.
[0053] According to an exemplary embodiment, a freewheeling working mode can be set. At this time, each high-power output circuit works independently, and devices such as diodes perform current sharing by themselves. A conduction mode is set, and different control switches are continuously switched on to conduct different high-power output circuits. Through time-division multiplexing of multiple different high-power output circuits, a driving output is continuously provided for the dynamic load. This avoids the problems of poor reliability and low efficiency caused by a single high-power output circuit driving a large load for a long time, and realizes high-efficiency, reliable, and flexible driving of high-power loads on the basis of effectively controlling the implementation cost.
[0054] An exemplary embodiment of the present disclosure further provides a high-power load processing method. The control strategy indicates that at least one group of high-power output circuits that are all independent of each other are conducted. At this time, the process of controlling the output of the high-power output circuit according to the control strategy is as Figure 3 shown, including: Step 301: Deploy the second connection points of each group of high-power output circuits according to the control strategy so that there is no connection between the second connection points.
[0055] In this step, the second connection points of each group of high-power output circuits are kept disconnected, and each group of high-power output circuits works independently.
[0056] Step 302: Send a control signal for driving the control switch to conduct to the control switch of the high-power output circuit indicated by the control strategy to be conducted.
[0057] In this step, according to the control strategy, a control signal is sent to the involved control switch to conduct the control switch, thereby realizing the conduction of the corresponding high-power output circuit. Specifically, a control signal indicating conduction can be sent according to the on-operation time carried in the control strategy; or after the off-duration expires, a control signal indicating conduction is generated and sent to the control switch.
[0058] According to an exemplary embodiment, a control signal indicating conduction may be sent to one or more control switches to respectively control multiple groups of high-power output circuits to supply power to corresponding dynamic loads.
[0059] After the switch is turned on, a control signal indicating turn-off may be sent according to the information of the turn-off operation time of the control switch carried in the control strategy; or a control signal indicating turn-off may be generated and sent after the on-duration is reached according to the information of the on-duration carried in the control strategy.
[0060] An exemplary embodiment of the present disclosure further provides a high-power load processing method. The control strategy indicates that at least two groups of high-power output circuits with electrical connections between the second connection points are turned on. At this time, according to the control strategy, the process of controlling the output of the high-power output circuit is as Figure 4 shown, including: Step 401: Deploy the second connection points of at least two groups of high-power output circuits according to the control strategy so that there are electrical connections between the second connection points.
[0061] In this step, when the control strategy indicates entering the conduction mode and multiple groups of high-power output circuits need to cooperate to supply power to the load, the second connection points of at least two groups of high-power output circuits involved are electrically connected. The dynamic load is connected in parallel between the first access point and the second access point, and the dynamic load is powered by the turned-on high-power output circuit.
[0062] Step 402: Send a control signal for driving the control switch of the high-power output circuit indicated by the control strategy to turn on to the control switch.
[0063] In this step, according to the control strategy, different control switches are turned on in a time-sharing manner, so as to continuously supply power to the load by switching the use of different high-power output circuits.
[0064] According to the control strategy, a control signal is sent to the corresponding control switch to control the control switch to turn on. Specifically, a control signal indicating turn-on may be sent according to the turn-on operation time carried in the control strategy; or a control signal indicating turn-on is generated and sent to the control switch after the off-duration is reached.
[0065] According to an exemplary embodiment, the control signal is a PWM signal. In this step, a PWM signal is generated, and each period of the PWM signal is used as the control signal for one or more control switches.
[0066] As Figure 5As shown, it is an example of a high-power load handling system, which includes n groups of high-power output circuits and a load L, and correspondingly includes n diodes (D1, D2, ……, Dn) and n control switches (SW1, SW2, ……, SWn). When controlling the switches through PWM signals, the PWM signals can be flexibly set according to factors such as hardware configuration and application requirements.
[0067] As Figure 6 shown, in method (1), only the high-power output circuits including SW1 and SW2 are used. The period of each PWM signal corresponds to the control signal of one control switch, and SW1 and SW2 are alternately controlled, thereby realizing the alternate conduction of SW1 and SW2. Specifically, in the T1 period, SW1 is controlled to conduct and turn off (ton and toff), in the T2 period, SW2 is controlled to conduct and turn off, in the T3 period, SW1 is controlled to conduct and turn off, in the T4 period, SW2 is controlled to conduct and turn off, and so on.
[0068] In method (2), the high-power output circuits including SW1, SW2, and SW3 are used. The period of each PWM signal corresponds to the control signal of one control switch, and SW1 SW2 SW3 are cyclically switched to conduct SW1, SW2, and SW3 in sequence. Specifically, in the T1 period, SW1 is controlled to conduct and turn off, in the T2 period, SW2 is controlled to conduct and turn off, in the T3 period, SW3 is controlled to conduct and turn off, and so on.
[0069] In method (3), the high-power output circuits including SW1, SW2, SW3, and SW4 are used. The period of each PWM signal corresponds to the control signal of one control switch, and SW1 SW2 SW3 SW4 are cyclically switched to conduct SW1, SW2, SW3, and SW4 in sequence. Specifically, in the T1 period, SW1 is controlled to conduct and turn off, in the T2 period, SW2 is controlled to conduct and turn off, in the T3 period, SW3 is controlled to conduct and turn off, in the T4 period, SW4 is controlled to conduct and turn off, and so on.
[0070] After the switch is turned on, a control signal indicating turn-off can be sent according to the information of the turn-off operation time of the control switch carried in the control strategy; or a control signal indicating turn-off can be generated and sent after reaching the on-duration carried in the control strategy. For PWM signals, a control signal indicating turn-off can be sent to the control switch conducting in this period at the end of this period.
[0071] An exemplary embodiment of the present invention further provides a high-power load processing system, which includes a controller and multiple groups of high-power output circuits. Figure 7 A high-power output circuit is shown, which is composed of a power supply (VDD), a load (L), a freewheeling diode (D), and a control switch SW (MOSFET).
[0072] Taking Figure 5 the shown high-power load processing system as an example, it includes n groups of high-power output circuits as Figure 7 shown. It should be noted that Figure 5 not all groups of high-power output circuits in
[0073] each have their own loads. According to an exemplary embodiment, one or more loads can be connected. When one or several groups of high-power output circuits are connected to a small-current load to work, at this time, each high-power output circuit works independently, and there is no electrical connection at the drain of each SW, that is, each group of high-power output circuits works independently of each other.
[0074] When connected to a large-current load to work, at this time, the SWs (MOSFET drains) of each group of high-power output circuits are connected together, and a control system with multiple paths is formed by multiple groups of high-power output circuits, and the large-current load is connected in parallel. Different turn-on modes can be set to control the time-sharing conduction of different paths of high-power output circuits to improve the output power.
[0075] According to an exemplary embodiment, two working modes, namely a freewheeling working mode and a conduction mode, can be set. In the freewheeling working mode, a load is connected in parallel on both sides of the diode, and the devices share the current by themselves; in the conduction mode, a PMW signal is used as a control signal to control the conduction of different SWs. In each PWM cycle, the power tubes of different low-side-driven high-power output circuits can be controlled to turn on. For example, in the first PWM cycle, the controller controls the power tube SW1 of the high-power output circuit 1 to turn on, and in the second PWM cycle, the controller controls the power tube SW2 of the high-power output circuit 2 to turn on, and so on in a cycle, and finally the system application function is completed.
[0076] An exemplary embodiment of the present disclosure further provides a high-power load processing device, which is applicable to the high-power load processing system provided by the embodiment of the present invention. The structure of the device is as Figure 8 shown, and includes: A policy acquisition module 801, which is used to acquire a control policy, and the control policy includes the turn-on and / or turn-off of at least one control switch.

[0080] Further, the control strategy instructs to turn on at least two sets of high-power output circuits with an electrical connection between the second connection points, and the output control module 802 further includes: The second deployment sub-module 903 is configured to deploy the second connection points of the at least two sets of high-power output circuits according to the control strategy so that there is an electrical connection between the second connection points.
[0081] The second control sub-module 904 is configured to send a control signal for driving the control switch to turn on to the control switch of the high-power output circuit instructed to turn on by the control strategy.
[0082] Further, the control strategy at least further includes any one or any combination of the following information: The turn-on operation time of each control switch, the turn-on duration of each control switch, the turn-off operation time of each control switch, and the turn-off duration of each control switch.
[0083] Further, the control signal is a PWM signal, and the second control sub-module 904 is specifically configured to generate a PWM signal according to the control strategy, and use each period of the PWM signal as the control signal for one or more control switches.
[0084] The above high-power load processing device can be integrated into a load driving device, such as an electric vehicle, etc., and the corresponding functions are implemented by the load driving device.
