Abstract

A power oscillator for driving a discharge lamp includes a bridge inverter as an oscillating circuit. The control signals for the oscillating circuit devices are provided by a current controlled oscillator which is controlled by a signal from a phase locked loop. The oscillator typically operates at frequencies between 3 and 30 MHz, and is suitable for driving inductively coupled discharges.
