Abstract

A high ignition voltage is required for the metal halide (MHD) lamp. In this paper, the ballast ignited by internal LC resonance of buck converter with minimum size is proposed. For minimizing the ignition current for device safety, the characteristic impedance is maximized. But this results In a large steady state ripple, which may cause the accoustic resonance. The steady state ripple cancellation network using the coupled inductor is proposed.
