A Zero Voltage Switching (ZVS) Boost Converter Suitable for Power Factor Correction

The paper addresses zero voltage switching (ZVS) boost converter that ensures to reduce the switching power losses and smart for the power factor correction as well as the wider range of the input voltages load variations. The boost diode of a standard boost converter is reinstated by auxiliary MOSFET ascertaining the turned off ZVS operations from the light load to full load conditions under the critical conduction mode (CRCM) and PWM control strategy to improve the input power factor.
