Abstract

Firstly, this paper establishes the equivalent circuit model of the proton exchange membrane electrolyzer (PEMEL) and verifies the effectiveness of the model based on experimental data. Then, a Three-Level(TL) buck converter is used to provide power for the PEMEL. Based on the average value model of the circuit, a Backstepping controller is designed to control the electrolysis voltage. Lastly, simulation is carried out based on Simulink/simscape software, the results show that compared with the PID controller, the Backstepping controller has shorter settling time and smaller overshoot.
