Abstract

[PROBLEMS] To obtain a controller capable of enhancing generation torque of an AC motor. [MEANS FOR SOLVING PROBLEMS] A controller for driving an AC motor through an inverter based on two or more power supplies including an energy storage element comprises a first inverter for converting a DC electricity supplied from the outside to an AC electricity, a power supply for storing the DC electricity, a second inverter for converting the DC electricity supplied from the power supply to an AC electricity, and an adder for adding AC
voltages on the output side of the first and second inverters.

Claims (4)

1. A controller for a variable speed alternating current motor, comprising:

two or more direct current power supplies including an energy accumulator;

two or more inverters for converting direct current voltages supplied from the two or more direct current power supplies into alternating current voltages; and a voltage adder for adding output voltages from the two or more inverters.
2. A controller for a variable speed alternating current motor, comprising:

a first inverter for converting direct current voltage supplied from a direct current power supply into alternating current voltage; and a second inverter for converting direct current voltage supplied from an energy accumulator into alternating current voltage, and then adding the alternating current voltage to the output voltage from the first inverter.
3. A controller for a variable speed alternating current motor, comprising:

two or more direct current power supplies including an energy accumulator;

two or more first inverters for converting direct current voltages supplied from the two or more direct current power supplies into alternating current voltages;

a voltage adder for adding output voltages from the two or more first inverters; and a second inverter for converting direct current voltage supplied from an energy accumulator into alternating current voltage, and then adding the alternating current voltage to the output voltage from the voltage adder.
4. The controller for a variable speed alternating current motor according to claim 1, further comprising means for switching between two or more direct current power supplies including an energy accumulator.
