Abstract
The proposed DC/AC power converter for transforming a DC input source to an AC output source includes a transformer having a primary and a secondary windings, a switch network having a first switch electrically connected between the DC input source and the primary winding, a two-way current-transmitting module electrically connected between the secondary winding and the AC output source and a controllable conducting circuit electrically connected to the secondary winding. In which, the controllable conducting circuit is conducting when the two-way current-transmitting module transmits an electrical energy from the primary winding to the secondary winding and a current flowing through the primary winding is decreasing so as to lower down a voltage stress of the first switch of the switch network.
