Abstract:
A mechanical power outputting apparatus for outputting mechanical power, said apparatus comprising:a first dynamo-electric motor driven to rotate by a polyphase alternating current; a first inverter circuit capable of supplying polyphase alternating-current power to said first dynamo-electric motor by switching operation of a plurality of switching elements; a first direct-current power supply connected with either bus of a positive pole bus and a negative pole bus of said first inverter circuit and a neutral point of said first dynamo-electric motor; a second dynamo-electric motor driven by a polyphase alternating current to rotate; a second inverter circuit having a positive pole bus and a negative pole bus connected with the positive pole bus and the negative pole bus of said first inverter circuit, respectively, said second inverter circuit supplying polyphase alternating-current power to said second dynamo-electric motor by the switching operation of the plural switching elements; and an accumulating device connected between the positive pole bus and the negative pole bus of said first inverter circuit, said accumulating device being capable of being charged and discharged.
