ABSTRACT:
This invention relates to a push-pull inverter used, for example, as a driver for cold-cathod discharge tube, hot-cathode discharge tube, etc.
According to this invention, respective control electrodes of a first switching element and a second switching element are interconnected by a capacitor so that a load current passes through this capacitor and thereby alternately activates the first and second switching element.
With such arrangement, a boosting transformer requires no feedback coil and it is possible to eliminate a capacitor for resonance which has conventionally been connected in parallel to a primary coil of said boosting transformer.
