[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0041] It should be noted that although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from the module division in the device or the flowchart.

[0042] Figure 1 It is a flowchart of a low-power standby control method for a switching power supply provided by an embodiment of the present invention. Among them, the switching power supply may but is not limited to include several functional units. Specifically, the functional units need to be determined accordingly according to different application scenarios, which are not limited herein. For example, in a common bidirectional switching power supply, it may but is not limited to include a PFC power supply unit, a DCDC unit, a driving unit (distinguishing the high-voltage side and the low-voltage side), a control unit, an auxiliary power supply (distinguishing the high-voltage side and the low-voltage side), a relay unit, a communication unit, and a sampling unit (distinguishing the high-voltage side and the low-voltage side), etc. Since the topological structure of the bidirectional switching power supply is well known to those skilled in the art, it will not be elaborated herein.

[0043] As Figure 1 shown, the low-power standby control method for the switching power supply may but is not limited to include steps S1000 to S4000.

[0044] Step S1000: Obtain the real-time power consumption of the switching power supply in the standby state;

[0045] Step S2000: When at least one target functional unit is screened from all functional units according to the real-time power consumption situation, perform a standby test on all target functional units to determine the standby mode of the switching power supply. Here, the target functional unit is a functional unit with standby power consumption, and the specific number of target functional units needs to be determined accordingly according to the actual scenario, which is not limited here. For example, in one case, the determined target functional units may include, but are not limited to, a communication unit, a high-voltage side driving unit, a low-voltage side driving power supply, a high-voltage side sampling unit, a low-voltage side sampling unit, a high-voltage side auxiliary power supply, a low-voltage side auxiliary power supply, a relay unit, a DCDC unit, a PFC power supply unit, etc.;

[0046] Step S3000: Determine the lowest-power consumption operation module corresponding to the switching power supply in the standby state according to all target functional units, the standby mode of the switching power supply, and the obtained preset operation requirement parameters of the switching power supply. Here, the lowest-power consumption operation module includes several target functional units, and the specific number, type, etc. of the target functional units included in the lowest-power consumption operation module need to be determined accordingly according to the actual scenario, which is not limited here;

[0047] Step S4000: Control the non-essential power consumption operation module separately from the lowest-power consumption operation module. Here, the non-essential power consumption operation module includes the remaining target functional units among all target functional units except the lowest-power consumption operation module.

[0048] In this step, by obtaining the real-time power consumption situation of the switching power supply in the standby state to screen the target functional units with standby power consumption, the standby mode of the switching power supply is determined. Furthermore, the lowest-power consumption operation module corresponding to the switching power supply in the standby state can be determined according to all target functional units, the standby mode of the switching power supply, and the preset operation requirement parameters of the switching power supply. Based on this lowest-power consumption operation module, the standby power consumption of the switching power supply can be effectively reduced; not only that, but the non-essential power consumption operation module different from the lowest-power consumption operation module is also controlled separately to minimize the standby power consumption of the non-essential power consumption operation module, so that the standby power consumption of the switching power supply is reduced within a controllable range; it can be seen that by performing low-power standby control on the switching power supply in the above manner, there is no need to delete circuits or change the topological structure of the original circuit during the whole process, so no new unstable structure factors will be introduced, thus ensuring good application stability of the switching power supply.

[0049] In one embodiment, the method for obtaining the real-time power consumption of the switched-mode power supply in the standby state in step S1000 can be various, and can be specifically set according to the actual scenario. For example, select a certain moment in the standby state, and respectively detect the real-time current and voltage of the functional units of the switched-mode power supply at the corresponding moment, so as to determine the standby power corresponding to the functional units at this moment. Similarly, if multiple moments are selected, the average value of the standby power at each moment can be calculated. That is to say, if it is detected that the standby power of the functional units at one or more moments in the standby state is relatively small, for example, if it is less than the preset standby power threshold, then it is determined that it does not belong to the target functional unit, otherwise it is determined that it belongs to the target functional unit. Or, further, determine the startup mode corresponding to the functional units at this moment, so as to determine the startup power required for the startup mode. Combining the previously determined standby power and startup power, the real-time power consumption of the switched-mode power supply in the standby state can be obtained, etc., which is not limited here.

[0050] As Figure 2 shown, in one embodiment of the present invention, step S2000 may but is not limited to include steps S2100 to S2300.

[0051] Step S2100: When it is determined that the switched-mode power supply enters the standby state, respectively obtain the current operating power of each target functional unit;

[0052] Step S2200: Obtain the sum of all the current operating powers to obtain the current standby power of the switched-mode power supply;

[0053] Step S2300: Determine the standby mode of the switched-mode power supply according to the magnitude relationship between the current standby power and the preset wake-up startup power.

[0054] In this step, on the premise of determining that the switched-mode power supply enters the standby state, the current standby power of the switched-mode power supply in the standby state is calculated by respectively obtaining the current operating power of each target functional unit. This current standby power represents the real-time power consumption of the switched-mode power supply in the current standby mode. Furthermore, according to the magnitude relationship between the current standby power and the preset wake-up startup power, the standby mode of the switched-mode power supply can be accurately and reliably determined.

[0055] It should be noted that the specific value of the wake-up startup power needs to be determined according to the actual application scenario, which is not limited here.

[0056] As Figure 3 shown, in one embodiment of the present invention, step S2300 may but is not limited to include step S2310.

[0057] Step S2310: When the current standby power is less than the wake-up power-on power, determine that the standby mode of the switching power supply is the natural standby mode; or, when the current standby power is greater than or equal to the wake-up power-on power, determine that the standby mode of the switching power supply is the wake-up standby mode.

[0058] In this step, if the current standby power is less than the wake-up power-on power, it means that the current standby power cannot meet the wake-up power-on requirement. Thus, it can be determined that the standby module of the switching power supply is not in the wake-up power-on mode but in the natural standby mode. Conversely, it can be determined that the standby mode of the switching power supply is the wake-up standby mode. Based on this, the corresponding target functional units required can be selected for the switching power supply according to its specific standby mode, with the aim of reducing the standby power consumption of the switching power supply to a reasonable range.

[0059] As Figure 4 shown, in an embodiment of the present invention, step S3000 may but is not limited to include steps S3100 to S3300.

[0060] Step S3100: According to the standby mode of the switching power supply, screen out a corresponding number of target functional units from all target functional units to form a first operation module;

[0061] Step S3200: According to the obtained preset operation requirement parameters of the switching power supply, screen out a corresponding number of target functional units from all target functional units to form a second operation module;

[0062] Step S3300: Determine that the lowest power consumption operation module corresponding to the switching power supply in the standby state includes the first operation module and the second operation module.

[0063] In this step, based on the standby mode of the switching power supply, a corresponding number of target functional units can be screened out from all target functional units to form a first operation module. For example, when the switching power supply is in the wake-up power-on mode, the first operation module with the lowest power consumption configured correspondingly may but is not limited to include a battery voltage sampling unit, a mains voltage sampling unit, a control unit, and an auxiliary unit, etc.; when the switching power supply is in the natural mode, the first operation module with the lowest power consumption configured correspondingly may but is not limited to include a control unit, a communication unit, and an auxiliary unit, etc.; and according to the preset operation requirement parameters, a corresponding number of target functional units can also be screened out from all target functional units to form a second operation module. That is to say, the first operation module and the second operation module are respectively the minimum power consumption modules matching the standby mode and the preset operation requirement parameters of the switching power supply. Then, by summarizing the two, the lowest power consumption operation module corresponding to the switching power supply in the standby state can be determined.

[0064] In one embodiment, the specific types, uses, etc. of the preset demand parameters can be various and need to be determined accordingly according to the actual application scenario, which is not limited here. For example, the preset operation demand parameters can include but are not limited to at least one of the following:

[0065] Response demand parameter, which represents that the switching power supply is used to receive an external instruction to exit the standby mode. For example, it can include but is not limited to configuring a corresponding wake-up unit for the switching power supply to match the response demand parameter. Among them, the wake-up unit can include but is not limited to a sampling unit. More specifically, such as a battery voltage sampling unit, a mains voltage sampling unit, etc.;

[0066] Feedback demand parameter, which represents that the switching power supply is used to feedback a processing signal according to the received external instruction. For example, it can include but is not limited to configuring a corresponding control unit for the switching power supply to match the feedback demand parameter;

[0067] Power demand parameter, which represents the charge and discharge demand of the switching power supply in the standby state. For example, it can include but is not limited to configuring a corresponding charge and discharge module for the switching power supply to match the power demand parameter. Among them, the charge and discharge module can include but is not limited to an auxiliary power supply, a sampling unit, and a control unit, etc.;

[0068] Network demand parameter, which represents the communication interaction demand of the switching power supply in the standby state. For example, it can include but is not limited to configuring a corresponding communication unit for the switching power supply to match the network demand parameter.

[0069] It should be noted that there may be duplicate situations for the modules or units respectively configured for each preset operation demand parameter. Considering that the switching power supply works as an integrated circuit, the modules or units involved in the duplication only need to be configured once.

[0070] As Figure 5 shown, in one embodiment of the present invention, step S4000 can include but is not limited to step S4100.

[0071] Step S4100: Control the on / off of the non-essential power consumption operation module through a pre-configured IO control unit, so that when the switching power supply is in the standby state, the non-essential power consumption operation module is in a stopped operation state.

[0072] In this step, after separating the non-essential power consumption operation module from the minimum power consumption operation module, the non-essential power consumption operation module is enabled by the IO control unit for on-off control, so that when the switching power supply is in the standby state, the non-essential power consumption operation module is in the stopped operation state. Similarly, when the switching power supply is about to enter the startup state or has entered the startup state, the non-essential power consumption operation module is controlled by the IO control unit to start and operate normally. That is to say, the on-off state of the non-essential power consumption operation module can be freely controlled by the IO control unit to match the actual application state of the switching power supply.

[0073] It should be noted that the IO control unit can but is not limited to adopting common IO control circuits in the art. This IO control circuit integrates corresponding switching elements, and the switching elements can usually be diodes, MOSFETs, IGBTs, etc. Specifically, the on-off control of the non-essential power consumption operation module is realized through the switching elements. Since this part of the circuit belongs to the related prior art well-known to those skilled in the art and is not the main inventive point of this application, it will not be elaborated here; as for the means of separating the non-essential power consumption operation module from the minimum power consumption operation module, there can be various methods. For example, the original circuit topology remains unchanged. On this basis, only the non-essential power consumption operation module and the minimum power consumption operation module are respectively arranged on different circuit branches, and each circuit branch is independently powered. Among them, on the circuit branch where the non-essential power consumption operation module is located, the IO control unit shown in the above embodiment is also provided, that is, the on-off of this circuit branch is controlled by the IO control unit.
