ABSTRACT:
The circuit utilizes a tertiary transformer for coupling a driving current to an inductive load. A switching transistor in series with the primary winding of the tertiary transformer initiates current flow thru the primary winding, which current, in turn, induces a current in the secondary winding of the tertiary transformer. The inductive load is connected across the secondary winding. The tertiary winding of the transformer is serially connected by a back-biased diode between the driving power source and a reference potential so as to quickly dissipate the energy stored in the secondary winding and the inductive load back to the driving power source when current in the primary winding ceases.
