Paper abstract:
This paper proposes the design and analysis of a multipulse rectifier fed multi-channel reconfigurable interleaved buck converter (IBC) for electrified hydrogen generation systems. Unlike existing topologies, this configuration utilizes a 24-pulse rectifier in the AC-DC stage to minimise grid current total harmonic distortion (THD) below 5% without any control circuit and additional filters on the grid side. In the DC-DC stage, a multi-channel reconfigurable interleaved buck converter (IBC) is employed to reduce the electrolyser current ripple and enhance lifetime. Further, a new control scheme is implemented that selectively activates the required number of channels based on the power demand for efficient and reliable operation. A dual loop control architecture comprising an inner current loop and outer voltage loop is implemented to regulate electrolyser voltage and current. The proposed system configuration, along with the selective reconfiguration scheme based on power demand, is validated using MATLAB simulations and experimental studies from a 1.2 kW laboratory prototype of the IBC stage.
