ABSTRACT:
A base drive circuit controller responsive to an external control signal indicative of the desired conduction of the upper or lower switching device of an inverter leg, provides control signals dependent on timing performed by a psuedo random counter. The external control signal can influence the controller operation only after a complete set of signals responsive to a preceeding transition of the external control signal has been completed. The base drive circuit controller is also responsive to feedback signals indicative of actual switching device conduction, and control signals responsive to the signals indicative of actual power switch conduction are provided to the base drive circuits.
