Abstract :
Previous studies of the LLC-type series resonant converter (LLC-SRC) have shown that this converter possesses much better control characteristics and lower component stresses compared with those of the conventional SRC. The authors extend previous work on the LLC-SRC by presenting a complete set of design curves and formulating a systematic design procedure for the converter. Based on the design procedure, a 150 W, 200 kHz, multi-output prototype converter has been designed and tested to verify the theoretical work. Experimental results under various load and line conditions and comparison to their theoretical values are presented
