ABSTRACT:
An electronic ballast circuit for a multiple gaseous lamp load includes a feedback rectifier circuit coupled to a high frequency inverter circuit and to a DC source. The high frequency inverter circuit is also coupled to the multiple gaseous load and a variation in an alterable impedance of the feedback rectifier circuit causes a variation in power applied to the multiple gaseous load and power provided by the DC source.
