ABSTRACT:
A series combination of thyristor and diode is connected across another series combination of thyristor and diode to form a bridge circuit. Serially connected reactor and capacitor are connected across one of the thyristor in the chopping control mode in the use of a DC source and disconnected from both thyristors in the phase control mode in the use of an AC source in order to drive a DC motor by either of the DC and AC sources. A battery can be connected across the bridge circuit through the DC motor. Either one of the series combinations may be formed of the diode and two thyristors one of which is always connected across the serially connected reactor and capacitor.
