ABSTRACT:
A protective circuit for a solid state static inverter which employs two groups of switching transistors coupled in push pull to the output transformer. If trigger pulses to one group of switching transistors is lost, the protective circuit senses the missing trigger pulses and disables both groups of switching transistors. In normal operation the protective circuit assures that only one group of switching transistors may be rendered conductive at any given time.
