An Input Current Feedback Method to Mitigate the DC-Side Low-Frequency Ripple Current in a Single-Phase Boost Inverter

语言:

中文摘要

Boost直流/交流逆变器广泛应用于基于低压直流源(如电池、燃料电池)的交流并网储能系统。该拓扑在直流侧产生的二倍频纹波电流会导致储能设备内部发热并加速性能衰减。本文提出一种输入电流反馈控制方法,旨在有效抑制直流侧低频纹波电流,提升储能系统的运行寿命与可靠性。

English Abstract

A boost DC/AC converter is popular in AC line-integrated energy storage systems (ESSs) based on low-voltage DC sources such as battery, fuel cell, or supercapacitor. The direct DC/AC power conversion in the boost inverter introduces a second-order harmonic ripple current at the DC side of the boost converter, which leads to internal heating of the energy storage devices and degradation of their li...
