一种抑制单相升压逆变器直流侧二倍频纹波电流的基于规则的控制器

A Rule-Based Controller to Mitigate DC-Side Second-Order Harmonic Current in a Single-Phase Boost Inverter

语言:

中文摘要

单级DC/AC升压逆变器在集成电池、燃料电池等储能设备至单相交流电网时具有优势。然而,逆变器直流侧产生的二倍频电流纹波会增加储能设备的内部损耗与发热,进而缩短其使用寿命。本文提出了一种基于规则的控制策略,旨在有效抑制该纹波电流。

English Abstract

Single conversion stage DC/AC boost inverters are an attractive solution when integrating energy storage devices, such as a battery, fuel cell, or supercapacitor to a single-phase AC grid. However, a second-order harmonic current ripple appears at the DC side of the inverter increasing the internal heat and losses in the energy storage device and degrading its lifetime. In this paper, a rule-based...
