摘要
Abstract
In view of a switching frequency reduction of the PWM rectifier power devices as well as an improvement of the anti-interference ability,a low switching frequency operation algorithm has thus been proposed based on an inverse model predictive control and an improved phase-locked loop control algorithm on the basis of LMS iterative algorithm control vector matrix so as to achieve fast tracking at the network end,thus weakening its influence,as well as improving the tracking efficiency of the phase-locked loop.A simulation analysis is conducted by using Matlab,with the results showing that the proposed strategy is characterized with a stable active and reactive power,a reduction in AC side current distortion rate,and a good performance in stability,thus verifying the effectiveness and feasibility of the proposed method.关键词
