Abstract

This paper studies the relationship between component tolerance and (1) total lamp current variation and (2) lamp current imbalance between lamps on one ballast. The PSPICE simulator and a four lamp fluorescent current-fed push pull inverter is used in the study. The concept of component quality level (CQL) is introduced. Components with different quality level and tolerance are selected and a normal distribution is assumed. The studies indicate that to meet lamp current tolerance specifications and to produce lowest cost products, it is not enough to just tighten the component tolerances. Both CQL and tolerance have to be considered
