Abstract
An inverter circuit having transistor switches connected to alternately and repetitively apply a-c electrical energy to a load such as a fluorescent lamp. An oscillator control circuit supplies control pulses to the transistor switches in a manner to control their switching to insure a symmetrical waveform at the load. D-C power for the oscillator control circuit is obtained by rectification of the a-c load energy, and the oscillator frequency is adjustable by means of a control voltage.
