Resumen: Among the main actions to inhibit greenhouse gases production is the replacement of fossil fuels by non-polluting alternatives, such as green hydrogen produced by an electrolyzer powered by a renewable energy source. This work develops a procedure to design and implement a switching regulator for the input current of a proton exchange membrane electrolyzer. The proposed scheme is based on a step-down converter. Starting from the linearized model of the combined converter-electrolyzer, a study of its dynamic behavior is carried out, establishing the controller scheme to be implemented as well as the most suitable feedback variables. The design procedure based on the parameters of the corresponding controller is described step by step. The improvements obtained in the dynamis of the input current of the electrolyzer by using the controller is shown by means of open and closed-loop simulation results.
