摘要
提出一种单周控制的三电平单相有源电力滤波器。它提高了系统承受的电压和功率等级,减小了功率器件承受的电压应力,控制器结构简单,具有控制精度高,补偿效果好的特点。适合于大功率高电压场合,易于推广到工业应用。在建立数学模型的基础上进行了仿真研究,仿真结果证明其具有很好的动静态补偿性能,能有效地补偿系统谐波,提高输电线功率因数和传输效率。
A three-level single-phase active power filter (APF) with one-cycle control is presented. It expends the voltage and power to the levels desirable for industrial applications, with less voltage stress on the semiconductor components, simplified circuit, high precision and effectual compensation. Simulation is carried out on the base of mathematic model. The simulation results verify that the three-level APF with one-cycle control can dynamically and effectually compensate the harmonics and reactive currents, it can improve power factor and transmission efficiency of transmission lines.
