直流融冰电流源PWM整流器的功率特性分析及有源阻尼与解耦控制研究
Research on Power Characteristics and Active Damping and Decoupling Control of Current Source PWM Rectifier for DC Ice-melting Application
摘要
Abstract
A current source pulse width modulation(PWM)rectifier has advantages of continuously adjustable current and strong capability to limit the short-circuit current,which is suitable for DC ice-melting application.However,it still has problems of a low switching frequency and a low filter cut-off frequency,possibly causing the problem of harmonic amplification.The active and reactive characteristics of the current source PWM converter are studied under constant-current load and constant-resistance load conditions,which is helpful in designing an LC filter to realize the high power factor of the rectifier.On the basis of stability analysis,a controller based on active damping and decoupling control is designed.Simulation results show that compared with the traditional non-decoupling control,the proposed method has better DC transient characteristics,so that it can effectively suppress lower-order harmonic current to eliminate the possible problem of harmonic amplification.关键词
