ABSTRACT:
A power inverter oscillator circuit has an output transformer with a primary winding, coupled in parallel with a capacitor, and the opposite ends of which are connected to the respective emitters of a PNP and a NPN transistors. The collector of the NPN transistor is coupled to the positive terminal and the collector of the PNP transistor is coupled to a negative terminal. In addition, a switching transformer is provided having a primary coil coupled at one end to one terminal and at the other end to the emitter of the transistor which is coupled to the other terminal. The switching transformer has two secondary coils or windings wherein one of the secondary coils is coupled between one terminal and the base of the transistor whose collector is coupled to the other terminal and the other secondary coil is coupled between the base of the other transistor and the remaining terminal.
