Design of Three-Phase Fully Controlled Type Rectifier Controller for Electrolytic Hydrogen Production System

In recent years, the rectifier technology has developed rapidly, the working index has been improved, the process characteristics are becoming more and more mature, and it has been widely used in many fields. In order to better cope with the volatility and instability of offshore wind-photovoltaic power coupled hydrogen production. In this paper, Clack transform, Park transform and Anti-Park transform are used to transform the coordinate system in the model establishment to achieve the experimental conditions required by the simulation. The Space Vector Pulse Width Modulation (SVPWM) algorithm is used to realize the efficient control of the system. The Proportional-Integral-Differential (PID) control method based on voltage outer loop and current inner loop is adopted. At the same time, LLCL filter with better filtering effect is selected and the model of three-phase full-control rectifier circuit proposed in this paper is built and simulated based on MATLAB/Simulink.
