摘要：

An auxiliary resonant tank-protected high-frequency electronic ballast is proposed in this paper. Based on the steady state analysis of the series resonant converter, the operational characteristics of the ballast circuit for metal halide (MH) lamps under different conditions are examined, and then potential hazards to the ballast circuit are addressed. To avoid those dangers, an auxiliary resonant tank is used for protecting the ballast circuit under all operations. With this auxiliary resonant tank, the reliability of the ballast can be improved significantly. Feasibility of the proposal for the ballast circuit is verified by analytical and experimental results obtained from the 150W prototype ballast.
