Abstract

An electronic starter using MOSFET is developed to take advantage of ideal preheating and starting features which can extend the lifetime of fluorescent lamps. The preheating curcuit of the developed electronic starter is consisted of three parts - a full wave rectifier curcuit, an FET switching curcuit, and a timer curcuit for the gate switching. The curcuit allows sufficient preheating current flow before the starting to protect lamp filaments, nevertheless it shortens the Preheating time and enables a single pulse ignition at the peak level of the line voltage. Experimental results show that fluorescent lamps of 20-40W range can be initiated within rather short time of $1{\sim}1.5sec$ with preheating current of 0.6A. The electronic starter withstands more than 70.000 cycles switchings without noticeable blackening due to anode spot. These features provide Proper evidences for the advantage of direct replacement with the new starter.
