Solid state electronic ballast system for fluorescent lamps

摘要

A high power factor ballast circuit for use with fluorescent lamps consisting of a power factor correcting inductor periodically saturated to store pulses of direct current energy and periodically discharge same at a regular periodic rate to power the fluorescent lamp. A bistable flip-flop circuit and an associated solid state switching device combine to periodically control the saturation and discharge of the inductor.
