摘要
Abstract
The topology structure of three-phase PWM voltage rectifier was introduced firstly and then analyzed the decoupling of the PWM rectifier. The simplified and controllable model of three-phase voltage source PWM rectifier can be realized by static and rotary coordinate transformation. The vector control based on rotary transformation could fail to decouple without accurate model and incomplete accordance between model parameters and system parameters which affects the system control performance. In order to achieve reliable and safe decoupling control,based on stator current decoupling control theory of induction motor, current internal model decoupling control strategy of three-phase voltage source PWM rectifier was proposed. The design and the scheme of the controller are given and all conclusions are supported by simulation. The results are favorable.关键词
