ABSTRACT:
A circuit for use with an electric motor being supplied by a DC voltage source is disclosed. More particularly, in accord with the invention, the circuit includes a main transistor which is adapted to be connected to the DC voltage source and which is connected to a commutating arrangement comprised of transistors arranged in a bridge circuit. Moreover, in further accord with the invention, the circuit is provided with a control device for supplying on-off commands to the transistors of the commutating arrangement and for controlling the main transistor such that it is provided with an off command of short duration at a time when one of the transistors of the commutating arrangement is being supplied with an on command.
