Burst mode resonant power converter with high conversion efficiency

摘要: A burst mode resonant power converter with high conversion efficiency has a rectifier, factor correction circuit, controller, and triggering unit. The maximum frequency switching end of the controller is connected to variable circuit. When load medium or heavy, circuit increases switch controller. in no-load light conditions, it reduces thereof. Therefore, number times that switches bridge conduction cycle 50% pulse signal output becomes longer. Larger energy can be transmitted at time secondary coil transformer. This overall efficiency.
