摘要： In one embodiment, a power converter system includes a first input terminal and a second input terminal operable to connect to an alternating current (AC) power source, and an output terminal at which an output voltage can be provided to a load. A first inductor and a first diode are connected in series between the first input terminal and the output terminal. A second inductor and a second diode are connected in series between the second input terminal and the output terminal. A first switch is connected to the first inductor and the first diode, and a second switch is connected to the second inductor and the second diode. The first switch and the second switch alternately function as a boost switch and a synchronous rectifier for charging and discharging the first and second inductors during operation of the power converter system. An auxiliary network is operable to provide for zero voltage switching (ZVS) and zero current switching (ZCS) conditions for both the first and second switches during operation of the power converter system.

摘要： An inverter and driving method of the inverter are disclosed. The inverter includes an active clamp forward (ACF) converter and a flyback converter. One of a forwarding operation of delivering current from a primary side to a secondary side by using the ACF converter and a backwarding operation of delivering current from the secondary side to the primary side by using the flyback converter is selected to generate a rectified AC.
