“…In the present work phase errors are avoided by synchronizing the switches of the IGBTs, so it is not needed an algorithm that uses additional computational resources. Reference [18] proposes a method for reducing circulating currents based on the virtual impedance concept. This technique is interesting when the parallel inverters are placed over a long distance without communication among units.…”

“…However, the control performance deteriorates when the system parameters are different in each converter module. A virtual impedance control method was proposed for current sharing and circulating current suppression [31,32]. However, these studies did not consider the mismatch of system impedance, which causes circulating currents to increase directly.…”
