Abstract

A voltage-loaded current-transform device for applying in a 3-phase A.C. motor is characterized that: There is a single D.C. power source whose positive terminal is connected to the common terminal of three power semiconductor switches. The other terminals of the three power semiconductor switches are connected respectively to the cathodes of three power diodes and the three winding terminals of Y-connection A.C. motor. The negative terminal of D.C. power source is connected to the anodes of the three power diodes and the winding's central point of the Y-connection A.C. motor. The gate control signal, which is generated by applying the winding's reference voltage of each phase and a triangle wave to a voltage comparator, is connected to a gate controller to drive the three power semiconductor switches to provide the required voltage for driving the 3-phase A.C. motor to run stably.
