- Abstract
This paper introduces a new boost converter-based soft switched active snubber cell for power factor correction. In this particular converter, the main switch is turned on through Zero Voltage Transition (ZVT) and is turned off with the aid of Zero Voltage Switching (ZVS). The main diode is turned on using ZVS and is turned off using Zero Current Switching (ZCS). In the active snubber cell, the auxiliary switch is turned on by means of ZCS and is turned off using Zero Current Transition (ZCT). No semiconductor device is exposed to additional voltage stress. In this paper, theoretical analysis of the proposed converter is exhibited and validated by both simulation and experimental studies while operating at 100 kHz switching frequency and 600 W output power. It is demonstrated that the proposed converter is of 95.7% efficiency and 0.99 unit power factor in the soft-switching operation.
