ABSTRACT:
Transistors or GTO's of an inverter are switched ON/OFF with a delay circuit which has a capacitor first charged at a forcing rate, then, held at an intermediary level, and which is first discharged at a forcing rate, then held at an intermediary level, thereby to provide underlap, minimum ON and OFF time control and noise filtering with a high precision.
