Abstract :
A new family of single-stage unity power factor converters is proposed. Although they operate in continuous conduction mode, a single switch is able to control the line current and the output voltage at the same time. The proposed structures are based on a three-state switch whose switching and conduction losses are similar to those of a conventional device
