ABSTRACT:
An unbalanced switching circuit is connected with a bi-directional control rectifier in such a manner that variance of counter electro motive forces produced by rotation of an AC motor affects the lower switching voltage in the unbalanced switching circuit through diodes and a capacitor to increase or decrease the conduction angle of the bi-directional control rectifier.
