摘要
Abstract
The mathematical model of three-phase voltage pulse width modulation (PWM) rectifier in the three-phaseabc stationary frame was introduced firstly. On this basis, the mathematical model of PWM rectifier based on deadbeat control (DBC) in the two-phase stationaryαβframe and its discrete method were analyzed. A current correction algorithm was proposed, which was based on "two-step prediction" of the reference current. This method could not only resolve the problem of delay compensation, but also reduce the sampling error. In the loop design, an outer loop control method was discussed which was based on the feedback variable of capacitor energy storage. Meanwhile, the estimated load power was feedforward to improve the anti-jamming capability. Finally, the experimental setup of PWM rectifier was built up in the laboratory, and then the practicability of the proposed control method is verified.关键词
