| Abstract: | Uncontrolled and half-controlled rectifiers cause power system harmonics and increasing serious reactive power.This paper adopts improved feed forward control strategy to design three-phase voltage-type PWM rectifiers.And the mathematical model and improved feed forward control strategy of rectifiers are analyzed.Then the simulation model is established under the MATLAB/simulink platform.Compared with the traditional PWM rectifiers,the simulation and test results show that the rectifiers can get a steady DC bus output voltage and it has good robustness. |
