Load Emulation for Electrolysis Rectifiers

Load emulation is a power hardware in the loop approach for testing rectifiers used for electrolysis in context of renewable energies. It enables development and testing of rectifiers without the need of a real electrolyzer with its peripherals. The demands for the application, a modular power electronic concept as well as a control system capable of fully reproducing the timing behavior of an electrolyzer, are presented. The approach is validated using a simulation model and measurements on a demonstrator circuit.
