In this paper, interleaved dual buck converters are analyzed for use with electrolyzers coupled to renewable energy sources. The topology offers advantages such as low blocking voltage stress, and the possibility to reach high current for large electrolyzers through interleaved connection of converter channels. Additionally, interleaved dual buck converters can generate points of current ripple cancellation for a discrete number of output voltage values, which increase as more channels are connected in interleaved mode. This can lead to a reduction in the power of each channel and extend the lifespan of the electrolyzer. The theoretical analysis of the converter and the dependence of the output current ripple on the different system variables and parameters are addressed. Simulation results are presented for a 6-channel interleaved configuration for a 1MW nominal power operating point, which can be reconfigured to 5 channels in order to reduce the output current ripple.
