Research of Three-level Shunt Active Power Filter Based on SVPWM

摘要: 文章建立了二极管钳位型三电平三相三线制并联型有源电力滤波器(APF)的数学模型,提出了一种将基于ip-iq法的指令电流计算、预测电流控制和空间矢量脉宽调制(SVPWM)相结合的并联型三电平有源电力滤波器的控制方案,分析了简化的三电平SVPWM控制算法。仿真和实验结果证明,该方案具有良好的谐波补偿效果,同时适合于全数字控制的DSP硬件实现和主回路保护,有较好的应用前景。

Abstract: The paper established a mathematical model of diode-clamped type three-level shunt active power filter(APF) with three-phase three-wire,put forward a control scheme of shunt three-level APF combining with calculation of instruction current based on i_p-i_q method,predictive current control and space vector pulse width modulation(SVPWM).It also analyzed simplified three-level SVPWM control algorithm.The result of simulation and experiment showed that the scheme has good compensation effect for harmonic wave,and is suited for DSP hardware realization and main circuit protection with full-digital control,has better application prospect.
