| Abstract: | The three-phase voltage source PWM rectifier principle, as well as the topology and the mathematical models under the abc, aft and dq frame reference are analyzed. The voltage oriented space vector control strategies and the virtual flux oriented space vector control strategies under the rotational dq frame reference are expounded. A three-phase voltage source PWM rectifier simulation platform is built with Simulink software, and the two types of PWM rectifier control strategies are simulated and the relevant comparative research are made. |
