High switching frequency operation, with converter loss kept at minimum, is possible through the use of Zero-Voltage Switching (ZVS) technique. High power factor operation can be achieved in Pulse Width Modulation (PWM) technique, since the input current is inherently close to sinusoidal due to the current injection PWM technique. High frequency operation is necessary to reduce the size of reactive components. Further, for MOSFET-based converters, ZVS is required for efficient operation to reduce or eliminate heat sink requirements. Resonant converters were well documented to meet both of these requirements. The aim of this work was to develop simulink models for Power Factor Correction (PFC) converter and closed loop DC to DC converter. In the present work, high frequency full bridge series resonant PFC converter with improved efficiency is designed and the simulation results are presented. [ABSTRACT FROM AUTHOR]
