Electrical power subsystems and methods for controlling same

Abstract:

A method for controlling an electrical power subsystem includes determining an auxiliary voltage error value based on a measured voltage of the low voltage distribution panel. The method further includes receiving an active current command. The method further includes calculating a switching pattern for a line-side converter of the power converter based on the auxiliary voltage error value and the active current command. A current level produced by the line-side converter controls a voltage to the low voltage distribution panel.
