Design of LCL Resonant Converter for Electrolyser
Résumé
An Electrolyser linked with a DC bus are analyzed and discussed in this paper.
An electrolyser is a part of renewable energy system which generates hydrogen from
water electrolysis. An LCL series parallel resonant converter (SPRC) for an electrolyser
application is simulated and implemented. A three element resonant converter capable of
driving voltage type load with load independent operation is analyzed. Detailed
experimental results obtained from a MOSFET based DC-DC resonant converter are
presented to verify the analysis. The MATLAB simulated results show that the output of
converter is free from the ripples, constant current, regulated output voltage and this type
of converter can be used for electrolyser application. This converter has advantages like
high power density, low EMI and reduced switching stresses. The simulation results are
verified with the experimental results.
