Optimal Parameter Design by NSGA-II and Taguchi Method for RCD Snubber Circuit

, 2022
A genetic algorithm and Taguchi method were used to optimize parameters for the residual-current device (RCD) snubber circuit of a DC-DC flyback converter. The most suitable algorithm was determined by using test functions to compare performance in three
