ENHANCED DESIGN APPROACHES FOR AN LLC RESONANT CONVERTER IN PEM ELECTROLYZER APPLICATIONS

Abstract

A resonant LLC converter is suggested in this study as a way to power a proton exchange 
membrane (PEM) electrolyzer. voltage overshoots must be avoided, the PEM needs a low voltage with a 
high current, output voltage disturbance must be kept to a minimum, and the converter's dynamic behavior 
must be overdamped. The design of the converter cuts down on switching and reverse recovery losses, 
which lets it meet the requirements of the design. The transmission losses in the output rectifier have the 
biggest effect on how well it works.
