Abstract
The push-pull converter for zero-voltage switching of the switches on the primary side of the transformer to have a relatively lower loss is proposed. Which includes: a transformer having a primary winding with a center tap and a secondary winding, an electrical energy storage device having a first terminal coupled to the center tap of the primary winding and a second terminal coupled to a ground, a first switch having a first terminal coupled to a first terminal of the primary winding and a second terminal coupled to the ground, a second switch having a first terminal coupled to the ground and a second terminal coupled to a second terminal of the primary winding, and a rectifier circuit coupled to the secondary winding for transforming an AC output of the secondary winding to a DC output.
