ABSTRACT:
An overlap control system is provided in a push-pull switching mode inverter power supply which prevents a second switching transistor from being turned on after a first switching transistor has been turned off until the end of the storage time of the transistor being turned off so as to prevent the conduction of through currents from one transistor to the other which would otherwise occur if the switch-over took place during the storage time, and which would cause high stress and failure of the switching transistors because there is no inherent limit to the magnitude of the through currents, and because the through currents do not pass through the load circuit of the power supply. The overlap control circuit of the invention permits operation of the power supply with up to 100% duty cycle without any possibility of damaging cross-conduction of the switching transistors to occur.
