Investigation of Snubber Capacitors Influence on the Operation of a Phase-Shift Controlled Series Resonant DC/DC Converter with Zero-Voltage Switching

摘要

The following paper considers investigation of snubber capacitors influence on the zero-voltage switching (ZVS) range of a phase-shift controlled series resonant DC/DC converter (PSC-SRC). The operating frequency is above the resonant frequency of the tank. On the basis of a theoretical analysis, the converter output voltage characteristics are obtained. The influence of the snubber capacitors is discussed. The theoretical results are compared to results obtained from a simulation examination of the converter.
