Abstract:
Active power converters and methods are presented for converting input electrical power to output electrical power with converter switching control in which the individual phase voltage command values are compensated according to phase line voltage imbalances to compensate the converter control to provide balanced phase currents in the presence of unbalanced phase supply line voltages.
