ABSTRACT:
Here is disclosed a push-pull inverter used to drive a cold cathode discharge tube, a hot cathode discharge tube and the like, comprising a boosting transformer having a first primary coil, a first secondary coil, a second primary coil and a second secondary coil; first and second switching elements each having a control electrode adapted for controllably interrupting primary current flowing through said first and second primary coils; a capacitor connected between the respective control electrodes of the respective switching elements; and a feedback circuit in which one end of the first secondary coil is connected to the control electrode of the first switching element and one end of the second secondary coil is connected to the control electrode of the second switching element so that load current from a load connected between the other ends of the respective first and second secondary coils flows through the capacitor.
