摘要

本文提出了一种最小化并联光伏逆变器间循环电流的方法。该方法基于共模电流测量和改变调制器开关频率。以前限制并联逆变器循环电流的方法在长距离中并不有效。该控制方法以无线方式工作,不受逆变器之间距离的限制。

Wireless circulating current control for parallel connected photovoltaic inverters
This paper presents a method for minimizing the circulating current between parallel connected photovoltaic inverters. The method is based on a common mode current measurement and on changing the modulator switching frequency. Prior methods for limiting circulating current in parallel connected inverters have not been efficient in long distances. The control method works wirelessly and is not limited by the distance between the inverters.
