| Abstract: | To further improve the efficiency of shaft generators, the shaft generator rectification system of Space Vector Pulse Width Modulation (SVPWM) rectifiers based on the feedforward decoupling control is built. A three phase SVPWM rectifier based on voltage current double loop control is adopted. The decoupling module including an outer voltage loop and an inner current loop can realize a decoupling control of the active and reactive power. Thus, the alternating current with changeable amplitude and frequency can be rectified to the stable direct voltage. The design parameters of Proportion Integration (PI) regulator of the inner current loop and the outer voltage loop are given. A simulation model is established by MATLAB/Simulink, and the feasibility of the control model is verified. Simulation results show that the rectifier is of fast dynamic response and good stability. |
