ABSTRACT:
A transformerless power oscillator for driving a high intensity electrodeless light bulb. The driver uses a silicon carbide static induction transistor (SIT) operating as a power oscillator powered by an unregulated power supply potential generated by a full wave rectifier bridge connected to an AC power line. A CW output signal is generated at S-band and is coupled to the excitation coil of an electrodeless lamp by means of a matching network.
