摘要
In an example embodiment, a method of controlling a three-phase alternating current (AC) voltage source includes determining an error between a direct current (DC) bus voltage command and a detected DC bus voltage, the detected DC bus voltage being a part of an outer feedback loop, obtaining one of a virtual conductance or virtual resistance, the one of the virtual conductance or the virtual resistance being a part of an inner feedback loop relative to the outer feedback loop, regulate an output DC bus voltage based on the error and the one of the virtual conductance or the virtual resistance and controlling the three-phase AC voltage source based on the regulation of the output DC bus voltage.
