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.
