In this paper is introduced a new family of DC-DC PWM converters using a true Zero Current and Zero Voltage Transition (ZCZVT) commutation cell. The soft-switching technique utilized provides Zero Current Switching (ZCS) and Zero Voltage Switching (ZVS) simultaneously, at both turn-on and turn-off of the main switch and ZVS for the main diode. The family of ZCZVT PWM converters is obtained from...

This paper presents the detailed analysis of a full bridge zero current switched (FB-ZCS) PWM converter that is suitable for high-voltage and high-power DC applications.

One of the difficulties with PWM switching converters is high switching loss and electromagnetic interference due to switching at non-zero voltage and current, which limits the operating frequency. In order to reduce the converter volume and weight (by increasing the frequency) and reducing switching losses, zero voltage and current switching methods are recommended. In this paper, four main ze...

An enhanced soft switching technique for an interleaved boost converter has better performance characteristics when compared to conventional boost converter. As IBC operates under soft switching the main devices do not have any additional voltage & current stress on the auxiliary devices are at low level. Where main switches operates out of phase and share the output current while providing sof...
