摘要

本文研究了具有对称I-V特性的级联h桥(CHB)低电容静态补偿器(LC-StatCom)中电容电压纹波对电流质量的影响。对h桥变换器在不同电容电压脉动下的总谐波畸变进行了分析。对350va的三单元CHB LC-StatCom系统进行了仿真分析，以证明LC-StatCom与传统的StatCom相比，能够提供高质量的电流。

LC-StatCom with symmetrical I-V characteristic: Total Harmonic Distortion Study

In this paper, the effect of capacitor voltage ripple on current quality in a cascaded H-bridge (CHB) low-capacitance static compensator (LC-StatCom) with symmetrical I-V characteristics is investigated. Total harmonic distortion of the synthesized ac voltage of an H-bridge converter operating with different capacitor voltage ripples is evaluated for both inductive and capacitive operating modes. Simulation-based analyses on a 350-VA three-cell CHB LC-StatCom system are provided to demonstrate LC-StatCom's effectiveness to provide high quality current compared to a conventional StatCom.
