Control method of asymmetric half-bridge power supply

The invention provides a control method of an asymmetric half-bridge power supply, and relates to the technical field of electronics, the power supply comprises a first arm switch and a second arm switch which form a half bridge, are used for controlling a resonance circuit and are controlled by a controller, and the control method comprises the following steps: providing a cluster mode, and controlling the first arm switch and the second arm switch in the cluster mode, the controller generates two groups of switching operation periods, the first group of switching operation periods and the second group of switching operation periods respectively comprise at least one switching period, the first arm switch and the second arm switch are only turned on once in each switching period, and the controller enables the first arm switch and the second arm switch to be turned off for neglect time from the end of the first group of switching operation periods; until the second set of switching operations begins.
