Abstract

This paper presents a two-stage acoustic resonance free electronic ballast for MHD lamps using peak-current control mode. The ballast is consisted of a PFC stage and a full bridge inverter to supply lamp with low-frequency square-wave current, which achieves acoustic resonance free operation. And due to the adoption of peak-current control mode, the current overshoot which is common during output current is well controlled. The proposed circuit was verified by simulation and experimental results.
