摘　　要：介绍了一种250W金卤灯电子镇流器,电路由PFC,Buck变换器和全桥逆变器组成为了避免声谐振,全桥逆变器工作在200llz低频方波。A prototype for 250 W metal halide lamps is introduced. the circuit topology is composed of a PFC. a buck con-verter and a full-bridge inverter. To avoid acoustie resonance, the fulI-bridge mverter is operated at 200Hz. the transtent and steady-state characteristics of metal halide lamps are measured and analyzed.

关 键 词：电子镇流器 金属卤化物灯 声谐振
