摘要

本文介绍了一种采用峰值电流控制方式的MHD灯用两级无声谐振电子镇流器。该镇流器由PFC级和全桥逆变器组成，为灯具提供低频方波电流，实现无声谐振工作。并且由于采用了峰值电流控制方式，很好地控制了输出电流中常见的电流超调。仿真和实验结果验证了所提电路的正确性。

A Two-Stage Low-Frequency Square-Wave Electronic Ballast for Metal Halide Lamps using Peak-Current Control Mode

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.
