Title: Gueorgui L. Grouev: Inventor of Electronic Ballast Technologies.

Introduction

Gueorgui L. Grouev is an inventor associated with Arlington Heights, Illinois. His work includes electronic ballast designs for operating gas-discharge lamps, with attention to lamp starting, flicker prevention, and reliable power delivery. He is credited with 3 patents.

Latest Patents

Grouev’s listed patents include “Electronic Ballast Having Open Circuit in Output.” The invention describes isolating gas-discharge lamps from the common rail when a ballast is in a quiescent state. A transistor in the current path becomes non-conducting, helping prevent flicker. The patent also describes alternative isolation approaches involving a semiconductor switch in the rectifier section or referencing the inverter output to the high-voltage rail.

Another listed patent is “Electronic Ballast with Cross-Coupled Outputs.” It describes operating groups of gas-discharge lamps through two inverters, with each inverter powering filaments in one group while supplying lamp current to the other group. This arrangement can keep lamps preheated for instant starting, even when one inverter is off. A network couples power to the filaments and is designed to be relatively insensitive to frequency changes.
