Design and Modeling of a 100W 1MHz GaN-Based Single-Switch Resonant Converter for High Power Density Inherent PFC LED Driver
Résumé
This paper presents the design of a 100W 1MHz single-switch GaN-based resonant converter for high power density LED driver. The proposed prototype is based on the class E topology and performs Zero Voltage Switching (ZVS) as well as inherent Power Factor Correction (PFC) capability. The design procedure using analytical equations is detailed. A high frequency model of the converter including PCB parasitic is achieved and simulation results are confronted to measurements. The designed converter shows an efficiency of 81 % for an output power of 100W at 1MHz.
