Abstract
In a multi-output power conversion circuit which drives a polyphase AC motor and another device but the polyphase AC motor using a DC power source, a transformer is connected to the neutral point of the polyphase AC motor, an AC voltage at a zero-phase voltage frequency is obtained from the transformer, and the other device is loaded with the AC voltage.
Claims8
A multi-output power conversion circuit supplying electric power from one DC power source to a polyphase AC motor and another device with the polyphase AC motor, comprising:
- a transformer of which the primary coil is connected to a neutral point of the polyphase AC motor and of which the secondary coil is connected to the other device.
A multi-output power conversion circuit supplying electric power from one DC power source to a polyphase AC motor and another device with the polyphase AC motor, comprising:
- a transformer, one terminal of which primary coil is connected to a neutral point of the polyphase AC motor, another terminal of which the primary coil is connected to a portion of half potential of the DC power source, and which the secondary coil is connected to the other device.
A multi-output power conversion circuit supplying electric power from one DC power source to a polyphase AC motor and another device with the polyphase AC motor, comprising:
- a transformer of which the primary coil is connected to a neutral point of the polyphase AC motor and of which the secondary coil is connected to the other device;
- and
- a capacitor, one of which terminals is connected to a neutral point of the polyphase AC motor, and another terminal of which is connected to a current phase driving the polyphase AC motor.
A power source which is connected to a DC power source and supplies a power source to a polyphase AC motor and another device, comprising;
- a conversion circuit converting output of the DC power source into an AC to be provided for the polyphase AC motor;
- a transformer connected to a neutral point of the polyphase AC motor;
- and
- a rectifying circuit rectifying output of the transformer and supplying the rectified output to the other device.
