摘要:
 针对可控整流器空间矢量脉宽调制( space vector pulse width modulation,SVPWM) 加入死区
后带来的波形畸变问题,分析了当前补偿补偿和无死区策略各自优点和存在的问题,提出了一种三
电平SVPWM 整流器死区作用范围闭环控制策略,该策略在控制系统原有的电压、电流双闭环基础
上添加了一个死区作用范围闭环,形成了三闭环控制系统。死区作用范围指的是一个周期内需要
加入死区时间的范围。死区作用范围闭环控制是指通过直流母线电压和有功功率检测对整流器在
不同工作状态下死区作用范围进行闭环控制的一种控制策略,抑制由于死区作用带来的谐波。仿
真和实验结果表明,加入死区作用范围闭环控制能够有效抑制整流器网侧电流谐波。
Abstract:
 In this paper,dead-zone compensation strategy and no-dead-zone strategies of space vector
pulse width modulation( SVPWM) for the controllable rectifier are discussed. A closed-loop control strategy
of the working range of the dead zone for three-level SVPWM rectifier is proposed. This strategy adds
the closed-loop control unit of the working range of the dead zone to the original voltage and current dualloop
closed-loop control system and forms a triple closed-loop control system. The working range of the
dead zone refers to the range which needs to add the dead zone in one cycle. Closed-loop control of the
working range of the dead zone refers to the dynamic closed-loop control on the working range of the dead
zone via the DC bus voltage and active power feedback according to the rectifier’s different working conditions.
It can suppress the harmonic due to the dead zone. Simulation and experimental results show that
the added closed-loop control of the working range of the dead zone can effectively suppress the rectifier
line-side current harmonics.
