摘要

本文介绍了一种HID灯的电子控制装置，该装置采用低频电流逆变器驱动灯，DC-DC降压变换器控制灯的电流和功率，以及基于断续导通模式升压变换器的功率因数预调节器。电源级的所有信号均由专用微控制器提供。概述了灯的工作阶段和避免声共振的策略。实现了一个没有声共振和频闪效应的70 W样机。这种方法可以很容易地扩展到其他额定功率。

Microcontrolled electronic gear for low wattage metal halide (MH) and high-pressure sodium (HPS) lamps

This paper presents an electronic control gear for HID lamps that operates with a low frequency current inverter to drive the lamp, a DC-DC buck converter to control the current and the power of the lamp and a power factor pre-regulator based on discontinuous conduction mode boost converter. All signals of the power stages are provided by a dedicated microcontroller. An overview of the lamp operation phases and the strategies to avoid acoustic resonance are mentioned. A 70 W prototype without acoustic resonance and stroboscope effect was implemented. The approach can be easily extended for other rated power.
