Abstract

The electronic ballast for MHD lamp was studied for automotive headlight application. Its basic principle is the Current Sourcing Push-Pull Resonant Inverter with DC I2Volt input Voltage. By changing the switching frequency according to the lamp state, the automotive requirement of very fast warm-up and the zero voltage switching condition were shown by the simulation of the ballast circuit.
