[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0015] It should be noted that although the functional modules are divided in the device schematic and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.

[0016] Figure 1 A flow chart of a low-power standby control method for a switching power supply provided in an embodiment of the present invention, wherein the switching power supply may include but is not limited to a plurality of functional units. Specifically, the functional units need to be determined accordingly according to different application scenarios, which are not limited here. For example, in a common bidirectional switching power supply, it may include but is not limited to a PFC power supply unit, a DCDC unit, a drive unit (distinguishing between a high-voltage side and a low-voltage side), a control unit, an auxiliary power supply (distinguishing between a high-voltage side and a low-voltage side), a relay unit, a communication unit, and a sampling unit (distinguishing between a high-voltage side and a low-voltage side) and other functional units. Since the topological structure of the bidirectional switching power supply is well known to those skilled in the art, it will not be described in detail here.

[0017] like Figure 1 As shown, the switching power supply low power standby control method may include but is not limited to steps S1000 to S4000.

[0018] Step S1000, obtaining the real-time power consumption of the switching power supply in the standby state; Step S2000: when at least one target functional unit is obtained from all functional units according to the real-time power consumption, a standby test is performed on all target functional units to determine the standby mode of the switching power supply, wherein the target functional unit is a functional unit with standby power consumption, and the specific number of the target functional units needs to be determined accordingly according to the actual scenario, which is not limited here. For example, the target functional units determined in one case may include but are not limited to a communication unit, a high-voltage side drive unit, a low-voltage side drive 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, and a PFC power supply unit, etc.; Step S3000: Determine the minimum 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 preset operation requirement parameters of the switching power supply obtained, wherein the minimum power consumption operation module includes a plurality of target functional units, and the specific number and type of the target functional units included in the minimum power consumption operation module need to be determined accordingly according to the actual scenario, and are not limited here; Step S4000: separately controlling the non-essential power consumption operation module from the minimum power consumption operation module, wherein the non-essential power consumption operation module includes the remaining target functional units in all target functional units except the minimum power consumption operation module.

[0019] In this step, the real-time power consumption of the switching power supply in the standby state is obtained to screen the target functional units with standby power consumption, so as to determine the standby mode of the switching power supply, and then the minimum 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, and the standby power consumption of the switching power supply can be effectively reduced based on the minimum power consumption operation module; not only that, the non-essential power consumption operation module different from the minimum power consumption operation module is also controlled separately, so as to reduce the standby power consumption of the non-essential power consumption operation module as much as possible, 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 of the switching power supply in the above manner, there is no need to delete the circuit or change the topology of the original circuit in the whole process, so no new unstable structural factors will be introduced, thereby ensuring that the switching power supply has good application stability.

[0020] In one embodiment, there may be multiple ways to obtain the real-time power consumption of the switching power supply in the standby state in step S1000, which may be specifically set according to the actual scenario. For example, a certain moment in the standby state is selected, and the real-time current and voltage of the functional unit of the switching power supply at the corresponding moment are respectively detected, so as to determine the standby power corresponding to the functional unit at the moment. Similarly, if multiple moments are selected, the average standby power of each moment may be calculated. That is to say, if it is detected that the standby power of the functional unit at one or more moments in the standby state is relatively small, for example, if it is less than a 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, the startup mode corresponding to the functional unit at the moment is determined, so as to determine the startup power required corresponding to the startup mode. Combined with the aforementioned determined standby power and startup power, the real-time power consumption of the switching power supply in the standby state can be obtained, etc., which is not limited here.

[0021] like Figure 2As shown, in one embodiment of the present invention, step S2000 may include but is not limited to steps S2100 to S2300.

[0022] Step S2100: when it is determined that the switch power supply enters the standby state, respectively obtain the current operating power of each target functional unit; Step S2200, obtaining the sum of all current operating powers to obtain the current standby power of the switching power supply; Step S2300: Determine the standby mode of the switching power supply according to the relationship between the current standby power and the preset wake-up power.

[0023] In this step, under the premise of determining that the switching power supply enters the standby state, the current operating power of each target functional unit is obtained respectively to calculate the current standby power of the switching power supply in the standby state. The current standby power represents the real-time power consumption of the switching power supply in the current standby mode. Then, according to the relationship between the current standby power and the preset wake-up power, the standby mode of the switching power supply can be accurately and reliably determined.

[0024] It should be noted that the specific value of the wake-up power needs to be determined according to the actual application scenario and is not limited here.

[0025] like Figure 3 As shown, in one embodiment of the present invention, step S2300 may include, but is not limited to, step S2310.

[0026] Step S2310: when the current standby power is less than the wake-up power, the standby mode of the switching power supply is determined to be the natural standby mode; or when the current standby power is greater than or equal to the wake-up power, the standby mode of the switching power supply is determined to be the wake-up standby mode.

[0027] In this step, if the current standby power is less than the wake-up power, it means that the current standby power does not meet the wake-up requirement, so it can be determined that the standby module of the switching power supply is not in the wake-up mode, but in the natural standby mode. Otherwise, it can be determined that the standby mode of the switching power supply is the wake-up standby mode. On this basis, the corresponding required target functional unit can be selected according to the specific standby mode of the switching power supply, so that the standby power consumption of the switching power supply can be reduced to a reasonable range.

[0028] like Figure 4 As shown, in one embodiment of the present invention, step S3000 may include but is not limited to steps S3100 to S3300.

[0029] Step S3100: According to the standby mode of the switching power supply, select corresponding target functional units from all target functional units to form a first operation module; Step S3200: According to the acquired preset operation requirement parameters of the switching power supply, a corresponding number of target functional units are selected from all target functional units to form a second operation module; Step S3300: Determine that the lowest power consumption operation module corresponding to the switch power supply in the standby state includes a first operation module and a second operation module.

[0030] In this step, based on the standby mode of the switching power supply, the corresponding target functional units can be screened out from all the target functional units to form a first operation module. For example, when the switching power supply is in the wake-up startup mode, the corresponding configured first operation module with the lowest power consumption may include but is not limited to a battery voltage sampling unit, a mains voltage sampling unit, a control unit, and an auxiliary unit; when the switching power supply is in the natural mode, the corresponding configured first operation module with the lowest power consumption may include but is not limited to a control unit, a communication unit, and an auxiliary unit; and according to the preset operation requirement parameters, the corresponding target functional units can also be screened out from all the target functional units to form a second operation module. That is to say, the first operation module and the second operation module are respectively used as the minimum power consumption modules matching the standby mode of the switching power supply and the preset operation requirement parameters, so the minimum power consumption operation module corresponding to the switching power supply in the standby state can be determined by summarizing the two.

[0031] In one embodiment, the specific types and uses of the preset demand parameters may 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 may include but are not limited to at least one of the following: A response requirement parameter characterizing that the switching power supply is used to receive an external instruction to exit the standby mode, for example, but not limited to, by configuring a corresponding wake-up unit for the switching power supply to match the response requirement parameter, wherein the wake-up unit may include, but not limited to, a sampling unit, more specifically, a battery voltage sampling unit, a mains voltage sampling unit, etc.; A feedback requirement parameter characterizing that the switching power supply is used to feedback a processing signal according to a received external instruction, for example, but not limited to, by configuring a corresponding control unit for the switching power supply to match the feedback requirement parameter; An electric energy demand parameter characterizing the charge and discharge demand of the switching power supply in the standby state, for example, but not limited to, configuring a corresponding charge and discharge module for the switching power supply to match the electric energy demand parameter, wherein the charge and discharge module may include, but not limited to, an auxiliary power supply, a sampling unit, and a control unit, etc.; The network requirement parameter characterizes the communication interaction requirement of the switching power supply in the standby state, and can be, for example but not limited to, configured with a corresponding communication unit for the switching power supply to match the network requirement parameter.

[0032] It should be noted that there may be duplication of modules or units configured for each preset operating requirement parameter. Considering that the switching power supply works as an integral circuit, the modules or units involved in duplication only need to be configured once.

[0033] like Figure 5 As shown, in one embodiment of the present invention, step S4000 may include, but is not limited to, step S4100.

[0034] Step S4100: The non-essential power consumption operation module is controlled on and off by a pre-configured IO control unit, so that when the switch power supply is in a standby state, the non-essential power consumption operation module is in a stopped operation state.

[0035] In this step, after distinguishing the non-essential power consumption operation module from the minimum power consumption operation module, the non-essential power consumption operation module is enabled through 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 a 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 up and run normally. In other words, 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.

[0036] It should be noted that the IO control unit can, but is not limited to, adopt the IO control circuit commonly used in the field. The IO control circuit is integrated with corresponding switching elements. The switching elements can generally be diodes, MOSFETs or IGBTs, etc. The on-off control of the non-essential power consumption operation module is specifically implemented through the switching elements. Since this part of the circuit belongs to the relevant prior art well known to those skilled in the art and is not the main invention point of the present application, it will not be described here. As for the means of distinguishing the non-essential power consumption operation module from the minimum power consumption operation module, there can be many means, such as keeping the original circuit topology unchanged. On this basis, it is only necessary to set the non-essential power consumption operation module and the minimum power consumption operation module on different circuit branches, and each circuit branch is independently powered. Among them, the circuit branch where the non-essential power consumption operation module is located is also provided with the IO control unit shown in the above embodiment, that is, the specific on-off of the circuit branch is controlled by the IO control unit.
