ABSTRACT:
The present invention teaches a magnetically coupled drive circuit for coupling isolated power switching transistors to low power dissipative control circuitry. Drive energy stored in the magnetic transformer is controllably varied between preselected minimum "turn-on" and dissipative maximum levels to concurrently insure turn-on/turn-off capability and minimize quiescent, steady state dissipation.
