摘要

收起

电流源脉冲宽度调制PWM（pulse width modulation）整流器具有输出电流连续可调、限制短路能力强的优点，适用于输电线路直流融冰的应用场景，但是也存在开关频率较低、滤波器截止频率低、可能引起谐波放大的问题。针对恒电流负载和恒电阻负载，研究电流源PWM整流器的有功和无功特性，有助于设计LC滤波器，实现整流器的高功率因数。在分析稳定性的基础上，设计有源阻尼和解耦的控制器。与传统的非解耦控制相比，仿真结果表明该方法具有更好的直流暂态特性，可以有效抑制低次的谐波电流，消除可能引起的谐波放大问题。

Abstract

收起

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.

Key words

Current source pulse width modulation (PWM) rectifier / power characteristic / low-order harmonic suppression / active damping and decoupling control
