Abstract

An exemplary power conversion system is disclosed including a DC bus for receiving DC power, a power converter for converting the DC power to AC power, and a controller. The controller generates a first command signal and a second command signal based on power command and feedback signals. Upon an negative sequence current occurrence, the converter controller generates first and second negative sequence current correction signals based on a detected grid current signal and a negative sequence current command signal, adjusts the first and second command signals based on the first and second negative sequence current correction signals respectively, and generates control signals for the power converter based on the adjusted first and second command signals to cause an AC voltage output from the power converter to reduce the negative sequence currents.
