Abstract

The purpose of this study is to examine the calculated method of loss characteristics of full-bridge eletronic ballast for 250Watt HID lamps by approximated modeling. These lamps have the most emit effiency and color rendering. Especially, the majority of losses appear to the MOSFET do full-bridge, L of output terminal and driver IC, besides losses occur to the R in the ballast. These losses cause heating and breakage of MOSFET. When HID-lamp arrivals the steady-state, loss of ballast is measured 9% and analyzed value is 8% approximately. Accordingly it is not too much to say that greater part of losses is examined.
