Abstract
The present invention discloses a switching control method for a dual auxiliary power supply comprising a master control module, a main auxiliary power supply, and a sleep auxiliary power supply, wherein the master control module controls the main auxiliary power supply by a switch control unit, and is further coupled to a trigger detection circuit powered by the sleep auxiliary power supply; and the main auxiliary power supply outputs a control signal to an energy conversion module. The sleep auxiliary power supply is constantly in an operation state; under the control of the switch control unit, (1) the main auxiliary power supply is in a locked state when no trigger signal is detected or the trigger signal is invalid, and (2) the main auxiliary power supply is in an operation state when a trigger signal is detected or a startup instruction is received.
