Alternating current motor drive circuit and electric vehicle drive circuit
To eliminate a need for a large volumetric reactor in a direct current chopper, achieving a downsizing of the circuit. A current source rectifier is provided at an output of an alternating current generator, an alternating current motor is connected to an output of the rectifier via a voltage source inverter, furthermore, two arms having switching elements connected in inverse parallel to diodes are connected to the output of the rectifier t, and one terminal of a direct current power source capable of a power supply and absorption is connected to a midpoint between the arms, while the other terminal thereof is connected to a neutral point of motor coils, achieving a solution of the problem.
