Review and Comparison of Resonant DC-DC Converters for Wide-Input Voltage Range Applications

This paper reviews and compares DC-DC resonant converters for wide input voltage range applications that can maintain high efficiency over such a wide voltage range. To meet such requirements, different methods have been reported in the open literature including topological switching between a half bridge (HB) and full bridge (FB) converters, increasing the magnetizing ratio, and using different rectifier types. Each method has its advantages and disadvantages. To help provide full understanding of advantages and disadvantages of these different methods, this paper will provide a comprehensive review of these methods and provide detailed performance comparison between them.
