四象限脉冲整流器控制策略研究与实现

摘要

针对四象限脉冲整流器,提出一种电压外环加电流内环的控制算法,详细介绍了该算法中基于d,q坐标系的有功无功电流解耦控制和基于广义二阶积分(SOGI)的单相锁相环技术.仿真和实验结果均证明该算法可实现直流侧电压稳定、网侧单位功率因数的控制目标.%A control algorithm of four-quadrant pulse rectifier is presented,it is a voltage outer loop and current inner loop control.The active and reactive current decoupling control based on d,q coordinate system and phase-locked loop(PLL) technology based on second order generalized integrated(SOGI) are introduced.The algorithm can achieve the goal of DC voltage stabilization and network side high power factor.
