Abstract

A push-pull inverter circuit for an inductive load such as a fluorescent lamp. A pair of transistors alternately and repetitively apply energy to the load, and are alternately rendered conductive by stored charges produced by flyback induced voltage in the load, in cooperation with a single mutual control circuit which repetitively renders the push-pull transistors nonconductive and removes their stored charges.
