摘要

本文研究了作为并联有源滤波器的五电平填充型u -cell (PUC5)及其改进型(MPUC5)。这些拓扑结构产生多电平电压,允许滤波器阻抗降低,并补偿谐波和无功功率,有助于满足IEEE标准。在元件数量、波形质量以及功率开关上的应力和损耗方面,将它们与级联h桥进行比较。在此基础上,给出了PUC5无传感器电压控制的拓扑结构、PWM和控制策略,并给出了仿真和实验结果。

PUC5 and MPUC5 Based Shunt Active Power Filters
This paper studies five-level packed U-cells (PUC5) and its modified version (MPUC5), both operating as shunt active power filters. These topologies generate multilevel voltages allowing filter impedance reduction, and compensate harmonic and reactive power helping to meet IEEE standards. They are compared with cascaded H-bridges in terms of number of components, quality waveforms, and stress and losses on power switches. Besides that, sensorless voltage control is presented for PUC5 topology, PWM and control strategies, simulation and experimental results are also presented.
