Design Flow of a Compact High-Frequency DC/DC Converter with Optimum Average Efficiency in a Wide Operation Range
The design of an LLC stage for a wide output voltage range imposes stringent challenges regarding electrical and thermal performance. To match these requirements this paper presents the design approach and measurements of a resonant LLC converter stage, optimized for a maximum average efficiency over a wide operating range.
