Abstract :
A new electronic ballast circuit for High Intensity Discharge (HID) lamps to achieve an "ultra" high efficiency of 95% is proposed In this paper. The first stage of the ballast which Is the power factor correction boost converter has demonstrated an efficiency of >97% using SI MOSFET as the switch. The second stage of the ballast, a DC to high frequency Inverter has been designed to achieve >98% efficiency. Thus the overall efficiency of the ballast Is expected to be >95%. The performance of the "ultra high" efficient electronic ballast when SIC MOSFETS are used Is discussed In the paper. A loss model has been developed to compare the efficiency of the electronic ballast when using Si or SiC devices.
