Abstract

This paper proposes a new ballast that is ignited by internal LC resonance of buck converter. In order to cancel the steady state current ripple, the proposed ballast utilizes the coupled inductor filter which minimizes the size and weight of the ballast. The operation mode of the proposed ballast is analyzed and the performance of the new ballast is verified by the experimental results from a HOW prototype ballast for metal halide discharge (MHD) lamp.
