Abstract

The high-frequency current-fed push-pull resonant inverter is suitable for fluorescent lamp electronic ballasts supplied by low DC voltages. The lamp stabilization can be either inductive or capacitive. This paper provides a comparative analysis, an analytic step-by-step design procedure, and a sensitivity analysis of lamp power due to component tolerances for both methods. A current crest factor analytical expression for capacitive stabilization is derived. Design performance is evaluated by measurements on a prototype
