Abstract
A control method for an active clamp converter has steps of: detecting a state of the load; when the state of the load is a light-load state, using a skipping mode to control a switch frequency of a master switch; when the state of the load is not the light-load state, using an ACF mode to control the switch frequency of the master switch. In the skipping mode, the switch frequency is decreased when the state of the load is getting light, thus providing an energy efficiency power saving function for the light-load state. In the ACF mode, the master switch is controlled to turn on while a reverse current is generated, thus the switching loss of the master switch is reduced.
