A Switching Control Method of Dual Auxiliary Power Supply

Abstract

The invention discloses a switching control method for dual auxiliary power supplies. The dual auxiliary power supplies comprise a master control module, a main auxiliary power supply and a dormant auxiliary power supply, wherein the master control module controls the main auxiliary power supply by a switch control unit and is also connected with a trigger detection circuit, power is supplied to the trigger detection circuit by the dormant auxiliary power supply, and the main auxiliary power supply outputs a control signal to an energy conversion module. The dormant auxiliary power supply is in a working state all the way, (1) the main auxiliary power supply is in a shunting state under the control of the switch control unit when a trigger signal is not detected by the trigger detection circuit or the trigger signal is failure; and (2) the main auxiliary power supply is in a working state under the control of the switch control unit after the trigger signal is detected by the trigger detection circuit or a start-up instruction is received by the master control module. By the switching control method for the dual auxiliary power supplies, standby energy consumption can be saved, and rapid response is achieved.

Description

technical field [0001] The invention relates to a switching control method of dual auxiliary power supplies. Background technique [0002] At present, most energy storage systems will only intervene and play a role when the power is interrupted or people need to use them. Under normal circumstances, the energy storage system is in a non-working state. In the non-working state, the energy storage system is required to consume no power or consume as little power as possible. At present, most of the energy storage systems are in the following two ways: first, the mechanical switch is used. When the energy storage system is not needed, the mechanical switch is turned off, and the energy storage system does not work at all. This method is costly, especially for large currents. Occasionally, the price of the mechanical switch is quite expensive, and the response is not timely, and the operation is cumbersome; the second is the direct standby mode, which has a large standby power ...

At present, most of the energy storage systems are in the following two ways: first, the mechanical switch is used. When the energy storage system is not needed, the mechanical switch is turned off, and the energy storage system does not work at all. This method is costly, especially for large currents. Occasionally, the price of the mechanical switch is quite expensive, and the response is not timely, and the operation is cumbersome; the second is the direct standby mode, which has a large standby power consumption due to the sampling of a single auxiliary power supply, resulting in a huge energy loss and increasing The number of charge and discharge cycles of the energy storage battery affects the battery life
