[0049] Embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure and should not be construed as limiting the present disclosure.

[0050] The present disclosure will be described in detail below in conjunction with specific embodiments.

[0051] In the first embodiment, as Figure 1 shown, Figure 1 is a schematic flowchart of a power supply control method provided by an embodiment of the present disclosure. The method can be implemented depending on a computer program and can run on a system for power supply control. The computer program can be integrated in an application or run as an independent tool-like application.

[0052] Among them, the power supply control method can be executed by an electronic product.

[0053] Exemplarily, the power supply control method includes the following steps:

[0054] S101, obtaining the input information and output information of the power supply;

[0055] According to some embodiments, the power supply includes, but is not limited to, a switching power supply, etc. Among them, a switching power supply, also known as a switched-mode power supply or a switching converter, is a high-frequency power conversion device and a type of power supply. The function of a switching power supply is to convert a voltage of one level into the voltage required by the user terminal through different forms of architectures and output the corresponding current. Existing control drivers are all composed of a main control part and a driving part, driving one or multiple motors, and the driving part of the motor mainly includes a driving chip. In order to effectively isolate the control power and the power, a multi-channel switching power supply is used for the power supply of the driving chip.

[0056] In some embodiments, the input information refers to information related to the input of the power supply. The input information includes, but is not limited to, the input voltage type and the input voltage value, etc.

[0057] Among them, the input voltage type refers to the voltage type of the input voltage received by the power supply. The voltage type includes, but is not limited to, DC voltage, AC voltage, etc.

[0058] In some embodiments, the output information refers to information related to the output of the power supply. The output information includes, but is not limited to, the output voltage type, the output voltage range, the number of output voltage paths, etc.

[0059] Among them, the output voltage type refers to the voltage type of the output voltage that the power supply needs to output. For example, the output voltage type includes DC voltage and AC voltage.

[0060] Among them, the output voltage range refers to the range of the output voltage that the power supply needs to output. For example, the output voltage range is from 10V to 40V. Among them, different output voltage ranges can be set according to different situations, and the embodiments of the present application do not limit this.

[0061] Among them, the number of output voltage paths refers to the number of output voltage paths that the power supply needs to output. For example, if the power supply needs to supply power to two load devices, the number of output voltage paths is 2; or, if the power supply needs to supply power to four load devices, the number of output voltage paths is 4.

[0062] S102, determine a control instruction according to the input information and the output information;

[0063] According to some embodiments, the control instruction is used to indicate the working mode and mode parameters of the power supply.

[0064] In some embodiments, the mode parameters refer to the specific parameters adopted when the power supply operates in a certain mode. For example, parameters such as the on-time and frequency of the switching transistor used.

[0065] S103, control the power supply according to the control instruction.

[0066] According to some embodiments, when controlling a power supply according to a control instruction, it is necessary to control both the circuit configuration of the power supply and the control method of the power supply simultaneously.

[0067] For example, when both the input voltage type and the output voltage type are direct current, the control instruction can indicate that the operating mode of the power supply is the direct current pulse width modulation (PWM) mode or the direct current pulse frequency modulation (PFM) mode, and indicate to switch the main circuit of the power supply to a direct current - direct current (DC - DC) voltage conversion circuit; when the input voltage type is alternating current and the output voltage type is direct current, the control instruction can indicate that the operating mode of the power supply is the alternating current PWM mode or the alternating current PFM mode, and indicate to switch the main circuit of the power supply to an alternating current - direct current (AC - DC) voltage conversion circuit.

[0068] In summary, the method provided in this embodiment can change the operating mode of the power supply with the changes in the input information and output information of the power supply, which is beneficial to improving the performance of power supply control, enhancing the power supply control accuracy, improving the output smoothness of the power supply, expanding the application range of the power supply, protecting the power supply itself, improving the stability of the power supply, and facilitating the stable control of the load.

[0069] This embodiment also provides another power supply control method. This method can be executed by an electronic product.

[0070] Exemplarily, this power supply control method can include the following steps:

[0071] S201, obtain the input information and output information of the power supply;

[0072] S202, determine a control instruction according to the input voltage type, input voltage value, output voltage type, output voltage range, and number of output voltage paths;

[0073] According to some embodiments, voltage type conversion information can be determined according to the input voltage type and output voltage type; voltage value conversion information can be determined according to the input voltage value and output voltage range; and a control instruction can be determined according to the voltage type conversion information, voltage value conversion information, and number of output voltage paths. Therefore, the mode of the main circuit of the power supply can be switched according to different input voltages or different working conditions to adapt to different applications.

[0074] In some embodiments, the voltage type conversion information and the number of output voltage paths can be used to determine the operating mode of the power supply, and the voltage value conversion information can be used to determine the mode parameters of the operating mode.

[0075] S203, obtain the working status information of the power supply;

[0076] According to some embodiments, the working status information refers to the status information of the power supply during operation. The working status information includes, but is not limited to, voltage information, current information, temperature information, and load information.

[0077] Among them, the voltage information includes, but is not limited to, input voltage value, output voltage value, output voltage range, number of output voltage paths, output voltage fluctuation value, etc.;

[0078] Among them, the current information includes, but is not limited to, output current value, etc.;

[0079] Among them, the temperature information includes, but is not limited to, the temperature value of the power supply, etc.

[0080] Among them, the load information is the load information of the power supply, and the load information includes, but is not limited to, load value, change value of the load, etc.

[0081] In some embodiments, the working status information of the power supply can be monitored by setting up a monitoring device. Therefore, it can provide reliable data support for the precise control of the power supply, improve the stability of the power supply. By monitoring different data and analyzing the data, the power supply can be better processed effectively and in real time, and the robustness of the power supply control can be improved.

[0082] Taking a scenario as an example, when the power supply adopts a switching power supply, the main circuit of the power supply is the core of the switching power supply, which is used to perform corresponding voltage conversion on the input voltage according to the working mode indicated by the control instruction, and output different voltages and currents. It includes a transformer unit, a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET, MOS) unit, and a rectification unit. Therefore, sensors can be respectively set in these units to monitor the working status information of the switching power supply.

[0083] Among them, the transformer unit is used to convert information according to the indicated voltage value and the number of output voltage paths, and adopt a corresponding laminated structure to ensure the reliability of the output.

[0084] Among them, the MOS unit is used to switch the number of MOSs through the switching unit according to the magnitude of the current to ensure the stability of the power supply output

[0085] Among them, the rectification unit is used to rectify the voltage input of the alternating current type into a suitable direct current type voltage output for facilitating subsequent control of the power supply.

[0086] S204. When the working state information meets the abnormal working conditions, determine an adjustment instruction;

[0087] According to some embodiments, when the voltage information meets the abnormal working conditions of the voltage, a voltage adjustment instruction can be determined.

[0088] In some embodiments, the voltage level corresponding to the output voltage value can be determined according to the correspondence between the voltage and the voltage level, and the voltage adjustment instruction can be determined according to the voltage level.

[0089] For example, when the output voltage value is greater than the first voltage threshold, the voltage level corresponding to the output voltage value is the overvoltage level; conversely, the voltage level corresponding to the output voltage value is the normal operation level.

[0090] Among them, the first voltage threshold does not specifically refer to a certain fixed threshold. The first voltage threshold can be determined according to the actual application scenario. For example, the first voltage threshold can be 1.2 times the rated output voltage.

[0091] Taking a scenario as an example, when it is monitored that the output voltage value of the power supply is greater than 1.2 times the rated output voltage, it is recognized that the voltage level is the overvoltage level. At this time, the voltage adjustment instruction is determined to reduce the chopping frequency until the output voltage value is less than 1.2 times the rated output voltage.

[0092] It should be noted that the overvoltage level can be further divided into multiple overvoltage sub-levels according to the overvoltage threshold sequence; then, after determining that the voltage level corresponding to the output voltage value is the overvoltage level, the position of the output voltage value in the overvoltage threshold sequence can be determined, so as to determine the overvoltage sub-level corresponding to the output voltage value.

[0093] Among them, the first overvoltage threshold in the overvoltage threshold sequence is the first voltage threshold, and the other overvoltage thresholds in the overvoltage threshold sequence except the first overvoltage threshold can be determined according to the actual application scenario.

[0094] Among them, the voltage range corresponding to the overvoltage level between the first overvoltage threshold and the second overvoltage threshold in the overvoltage threshold sequence is the first-level overvoltage sub-level, and the subsequent overvoltage sub-levels can be obtained by analogy. Each overvoltage sub-level can also correspond to a chopping frequency reduction value. Since the lower the level of the overvoltage sub-level, the lower the overvoltage degree, therefore, the lower the level of the overvoltage sub-level, the lower the corresponding chopping frequency reduction value. The chopping frequency reduction value corresponding to each overvoltage sub-level can also be adjusted according to the actual application scenario.

[0095] Secondly, the normal level can be further divided into multiple normal operating voltage levels according to the normal operating voltage threshold sequence; then, after determining that the voltage level corresponding to the output voltage value is the normal operating level, the position of the output voltage value in the normal operating voltage threshold sequence can be determined, so as to determine the normal operating voltage level corresponding to the output voltage value.

[0096] Among them, the first normal operating voltage threshold in the normal operating voltage threshold sequence is the first voltage threshold, and the other normal operating voltage thresholds in the normal operating voltage sequence can be determined according to the actual application scenario.

[0097] Among them, the normal operating voltage level corresponding to the voltage range between the first normal operating voltage threshold and the second normal operating voltage threshold in the normal operating voltage sequence is the first-level normal operating voltage level, and the subsequent normal operating voltage levels can be obtained by analogy. In addition, the lower the level of the normal operating voltage level, the closer it is to the first voltage threshold, the higher the risk of it turning into an overvoltage level, and the more it needs to be monitored keyly.

[0098] According to some embodiments, when the current information meets the abnormal working conditions of the current, a current adjustment instruction can be determined.

[0099] In some embodiments, the current level corresponding to the output current value can be determined according to the correspondence between the current and the current level, and the current adjustment instruction can be determined according to the current level.

[0100] For example, when the current is greater than the first current threshold, the current level corresponding to the current is the overcurrent level; when the duration for which the current is greater than the second current threshold is greater than the first duration threshold, the current level corresponding to the current is the overcurrent level; in other cases, the current level corresponding to the current is the normal operating level.

[0101] Among them, the first current threshold is greater than the second current threshold, and the first current threshold and the second current threshold do not specifically refer to a certain fixed threshold. The first current threshold and the second current threshold can be determined according to the actual application scenario. For example, the first current threshold can be 2 times the output rated current, and the second current threshold can be 1.1 times the output rated current.

[0102] Taking a scenario as an example, when it is monitored that the output current value of the power supply is greater than 2 times the output rated current, or the duration for which it is greater than 1.1 times the output rated current is greater than the first duration threshold, it is recognized that the current level is the overcurrent level. At this time, the current adjustment instruction is determined to be the output of reducing the control ability, and the output current value of the power supply is monitored again until the output current value is less than 1.1 times the output rated current, it is recognized that the power supply returns to normal, otherwise the control ability is continuously reduced until shutdown.

[0103] It should be noted that the overcurrent level can be further divided into multiple overcurrent sub-levels according to the overcurrent threshold sequence; then, after determining that the current level corresponding to the output current value is the overcurrent level, the position of the output current value in the overcurrent threshold sequence can be determined, so as to determine the overcurrent sub-level corresponding to the output current value.

[0104] Among them, the first overcurrent threshold in the overcurrent threshold sequence can be the second current threshold, and the other overcurrent thresholds in the overcurrent threshold sequence except the first overcurrent threshold can be determined according to the actual application scenario.

[0105] Among them, the overcurrent level corresponding to the current range between the first overcurrent threshold and the second overcurrent threshold in the overcurrent threshold sequence is the first-level overcurrent sub-level, and the subsequent overcurrent sub-levels can be obtained by analogy. Each overcurrent sub-level can also correspond to a chopping frequency reduction value. Since the lower the level of the overcurrent sub-level, the lower its overcurrent degree, therefore, the lower the level of the overcurrent sub-level, the lower the corresponding control ability reduction value, and the control ability reduction value corresponding to each overcurrent sub-level can also be adjusted according to the actual application scenario.

[0106] Secondly, the normal level can also be further divided into multiple current normal operation levels according to the normal operation current threshold sequence; then, after determining that the current level corresponding to the output current value is the normal operation level, the position of the output current value in the normal operation current threshold sequence can be determined, so as to determine the current normal operation level corresponding to the output current value.

[0107] Among them, the first normal operation current threshold in the normal operation current threshold sequence can be the second current threshold, and the other normal operation current thresholds in the normal operation current sequence except the first normal operation current threshold can be determined according to the actual application scenario.

[0108] Among them, the normal operation current level corresponding to the current range between the first normal operation current threshold and the second normal operation current threshold in the normal operation current sequence is the first-level normal operation current level, and the subsequent normal operation current levels can be obtained by analogy. In addition, the lower the level of the normal operation current level, the closer it is to the second current threshold, the higher the risk of it turning into the overcurrent level, and the more it needs to be monitored keyly.

[0109] According to some embodiments, in the case where the temperature information meets the abnormal temperature working conditions, a temperature adjustment instruction can be determined.

[0110] In some embodiments, the temperature level corresponding to the temperature information can be determined according to the correspondence between the temperature and the temperature level, and the temperature adjustment instruction can be determined according to the temperature level.

[0111] For example, when the duration for which the temperature value is greater than the temperature threshold is greater than the second duration threshold, the temperature level corresponding to the temperature information is the over-temperature level; otherwise, the temperature level corresponding to the temperature information is the normal operation level.

[0112] Among them, the temperature threshold does not specifically refer to a fixed threshold. The temperature threshold can be determined according to the actual application scenario. For example, the temperature threshold can be 80 degrees Celsius.

[0113] Taking a scenario as an example, when it is monitored that the duration for which the temperature value of the power supply is greater than 80 degrees Celsius is greater than 2 minutes, the excessive temperature will affect the power supply. Therefore, it is determined that the temperature adjustment instruction is to control the power supply within a relative output range, that is, a specific output voltage range, until the temperature drops to a reasonable range and then normal control is carried out.

[0114] It should be noted that the over-temperature level can be further divided into multiple over-temperature sub-levels according to the over-temperature sub-threshold sequence; then, after determining that the temperature level corresponding to the temperature information is the over-temperature level, the position of the temperature value in the over-temperature sub-threshold sequence can be determined, so as to determine the over-temperature sub-level corresponding to the temperature value.

[0115] Among them, the first over-temperature sub-threshold in the over-temperature sub-threshold sequence is the temperature threshold, and the other over-temperature sub-thresholds in the over-temperature sub-threshold sequence except the first over-temperature sub-threshold can be determined according to the actual application scenario.

[0116] Among them, the over-temperature level corresponding to the temperature range between the first over-temperature sub-threshold and the second over-temperature sub-threshold in the over-temperature sub-threshold sequence is the first-level over-temperature sub-level, and the subsequent over-temperature sub-levels can be obtained by analogy. Each over-temperature sub-level can also correspond to an output voltage range. Since the lower the level of the over-temperature sub-level, the lower the over-temperature degree, therefore, the lower the level of the over-temperature sub-level, the larger the corresponding output voltage range can be, and the output voltage range corresponding to each over-temperature sub-level can also be adjusted according to the actual application scenario.

[0117] Secondly, the normal level can also be further divided into multiple normal operation temperature levels according to the normal operation temperature threshold sequence; then, after determining that the temperature level corresponding to the temperature information is the normal operation level, the position of the temperature value in the normal operation temperature threshold sequence can be determined, so as to determine the normal operation temperature level corresponding to the temperature value.

[0118] Among them, the first normal operation temperature threshold in the normal operation temperature threshold sequence is the temperature threshold, and the other normal operation temperature thresholds in the normal operation temperature sequence except the first normal operation temperature threshold can be determined according to the actual application scenario.

[0119] Among them, the normal operating temperature level corresponding to the temperature range between the first normal operating temperature threshold and the second normal operating temperature threshold in the normal operating temperature sequence is the first-level normal operating temperature level, and subsequent normal operating temperature levels can be obtained by analogy. In addition, the lower the level of the normal operating temperature level, the closer it is to the temperature threshold, the higher the risk of it transitioning to the over-temperature level, and the more it needs to be monitored closely.

[0120] According to some embodiments, when the load information meets the drive adjustment requirements, it indicates that the power load has changed. To meet the output capacity of the drive, it is necessary to adjust the control instruction of the power supply to ensure the output capacity of the power supply. Therefore, it is necessary to determine the load adjustment instruction.

[0121] In some embodiments, when determining the load adjustment instruction, when the voltage information meets the first preset condition, the load adjustment instruction is determined to be changing the output time of the power supply; when the voltage information meets the second preset condition, the load adjustment instruction is determined to be changing the on-time of the power supply switch tube.

[0122] In some embodiments, the first preset condition can be, for example, that the voltage level corresponding to the voltage information is greater than the second voltage threshold, and the second preset condition can be, for example, that the voltage level corresponding to the voltage information is greater than the third voltage threshold.

[0123] Among them, the second voltage threshold and the third voltage threshold do not specifically refer to a certain fixed threshold. The second voltage threshold and the third voltage threshold can be determined according to the actual application scenario. For example, the second voltage threshold can be 1.03 times the rated output voltage, and the third voltage threshold can be 1.05 times the rated output voltage.

[0124] It should be noted that the measurement of the load information can be carried out when it is detected that the change amount of the drive load is greater than the change amount threshold, and it is judged whether the load information meets the drive adjustment requirements.

[0125] S205, adjust the control instruction according to the adjustment instruction, and control the power supply according to the adjusted control instruction.

[0126] In summary, the method provided in this embodiment can be compatible with different voltage levels and different voltage types by adding operating modes for different input voltages. It can adapt to sudden changes in the load, change its own output capacity and output mode according to the operating state of the driver, ensure that the power supply can work effectively at different voltage levels of the driver, ensure the universality of the power supply, improve the applicability, and ensure that stable voltage and current can be output under different working environments and different driving loads, which is beneficial to improving the performance of the driver and increasing the reliability and stability of the power supply. Secondly, it also has various protection functions, not only overvoltage and over-temperature protection but also overcurrent protection, enabling the power supply to operate within a reasonable working temperature, improving the service performance of the power supply, extending the life of the power supply, ensuring the stable and reliable operation of the power supply, reducing the later maintenance and repair costs, and being beneficial to increasing the economic benefits of the enterprise.
