有源电力滤波器已被证明能有效地消除电力线路中的无功和谐波电流。以前提出的大多数方法都是基于两电平逆变器，因此适合于低电压应用。本文提出了三电平三相有源电力滤波器的拓扑结构和控制方法，将电压和功率扩展到工业应用所需的水平。所提出的单周控制三相有源电力滤波器具有工作电压高、半导体元件电压应力小、控制电路简单的特点，不需要参考计算、dq变换和乘法器。基于一台1kW样机的实验室实验结果表明，该系统具有良好的谐波抑制能力和刚性鲁棒性。
Active power filters have been reported effective in eliminating the reactive and harmonic current in the power lines. Most previously proposed methods are based on two level inverters and thus are suitable for low voltage use. In this paper, topologies and control are proposed for three-level three-phase active power filters that expend the voltage and power to the levels desirable for industrial applications. The proposed three-phase active power filter with one-cycle control features high voltage operation with reduced voltage stress on the semiconductor components and simple control circuitry that needs no reference calculation, dq conversion, nor multipliers. Laboratory experimental results based on a 1 kW prototype have demonstrated excellent harmonic suppression capability and rigid robustness.
