Abstract
This paper presents a method for minimizing thecirculating current between parallel connected photovoltaicinverters. The method is based on a common mode currentmeasurement and on changing the modulator switchingfrequency. Prior methods for limiting circulating current inparallel connected inverters have not been efficient in longdistances. The control method works wirelessly and is not limitedby the distance between the inverters.
