Analysis and Simulation of Novel RCD Passive Snubber Cell for Flyback Dc-Dc Converters
Journal Title: Rahva Journal of Technical and Social Studies - Year 2021, Vol 1, Issue 1
Abstract
Pulse Width Modulation (PWM) flyback dc-dc converters are pretty popular and have wide range application in the industry. Nevertheless, the leakage inductance issues cause high voltage spikes on the semiconductor switch when it is turned off. Consequently, passive or active snubber cells are needed at turned-off process for limiting the voltage spikes. In this paper, a novel passive snubber cell is proposed for PWM flyback dc-dc converter. The proposed snubber cell has low cost, ease of control and simple structure features. The detailed theoretical analysis of converter is presented and the analysis is demonstrated by a simulation setup in the paper. All analyses and simulation setup is made under 100 kHz switching frequency and 16 W output power conditions.
