20150333667 | ELECTRIC MOTOR DRIVING DEVICE - A decrease of inductance in a carrier frequency region being used is suppressed by connecting reactors capable of maintaining a fluctuation range of inductance within a predetermined range in the carrier frequency region in series to and between an inverter device converting electric power of an energy storage device and an electric motor. Consequently, the electric motor is controlled while an iron loss and an electromagnetic noise are reduced independently of characteristics of an iron material and a magnetic steel sheet material used as a core material of the electric motor. | 11-19-2015 |
