—High switching frequency associated with soft commutation techniques is a new trend in switching converters. Following this trend, the authors present a buck pulsewidth modulation converter, where the dc voltage conversion ratio has a quadratic dependence on duty cycle, providing a large step-down. By introducing two resonant networks, soft switching is… (More)
High power factor, high frequency single stage single switch resonant inverter for the application of high frequency applications is presented in this paper. The power circuit is designed with a power factor corrector with single-switch current-fed high frequency resonant inverter. Number of switches used in conventional ballast circuits is reduced in… (More)
In this paper an approach of a step-up/down dc-dc converter with wide range conversion called Boost 2-Buck is presented. The proposed converter presents nonpulsating input and output current. It has operations equivalent to a cascade converter consisting of two boost converter and one buck converter, but with the advantage of using single active switch.… (More)
