Abstract
The shortcomings of zero-voltage-transition PWM converter is discussed and a new family of topologies of zero-voltage-transition PWM converter with soft-switched auxiliary switch is introduced. The experiments on a 290W boost converter and a 100W forward converter are carried out to prove the circuit. The efficiency increment of the new circuits are 2-5% comparing to hard switching circuits, and the switching noise is also greatly reduced.
