Abstract:
1. An electric power converter for controlling feed voltages from plural power sources and driving a multi phase AC motor, the converter comprising: an electric power conversion circuit; and an electric power controller operable to control switching devices of the electric power conversion circuit to generate a driving voltage for driving at least a first phase of the motor by generating pulses from output voltages of the plural power sources; to generate a driving voltage for driving a different phase of the motor by generating pulses from an output voltage of only one of the plural power sources; and to generate pulses of a first ON time average value for each period of an electrical angle for switching devices of the first phase, the pulses corresponding to an allotment instruction of electric power of the plural power sources; and wherein the first ON time average value is different from a second ON time average value for each period of the electrical angle of the different phase.
