ABSTRACT:
A drive circuit for a voltage controlled power switching device includes a transformer, a full-wave rectifier bridge coupled to the transformer, first and second capacitors connected in series between nodes of the full-wave rectifier bridge and first and second controlled switches coupled between a control electrode of the power switching device and the first and second capacitors, respectively, wherein each controlled switch has a control electrode coupled to a secondary winding of the trans-former. Current is provided by the first capacitor to the control electrode of the power switching device through the first controlled switch at the beginning of a negative pulse appearing at the secondary winding of the transformer and charging current is provided to the first capacitor from the secondary winding of the transformer through the full-wave rectifier bridge after the beginning of the negative secondary pulse. Current is drawn from the control electrode of the power switching device through the second controlled switch to the second capacitor at the beginning of a positive pulse appearing across the secondary winding and charging current is provided to the second capacitor from the secondary winding of the transformer through the full-wave rectifier bridge after the beginning of the positive pulse.
