Fuzzy logic control of resonant converters for power supplies

Fuzzy logic control (FLC) technology has drastically reduced the development time and deployment cost for the synthesis of nonlinear controllers for dynamic systems. As a result there have been an increased number of FLC applications. The authors illustrate their efforts in FLC technology transfer aimed at controlling a resonant converter power supply. The authors discuss the development of FLCs for a series-resonant converter (SRC) and a single-ended parallel multi-resonant converter (SEP-MRC). The authors emphasize the role of fuzzy logic in the development and deployment of these applications, and show how to meet their stringent throughput requirements by compiling the FLC into look-up tables
