应用于场馆灯的智能调光器设计

AC transformer dimmer design for stadium lights

本文介绍一种适用于场馆灯的智能调光器,这种调光器可以将电网的正弦波交流电压转换为可调电压的正弦波交流电。主要采用了交流斩波调压技术和带电流电压检测的非互补控制方式。可以根据光源的要求,在大范围内调光。适用于各种负载特性(阻性、感性、容性)的光源的调光控制。波形失真度小,效率高,动态响应快。调光器具有完备的保护功能,有较高的可靠性。

This paper presents a AC dimmer for stadium lights.This dimmer can transfer AC voltage of the grid into Adjustable voltage AC sine wave.It mainly used the technology of AC Chopper voltage regulator and method of non-complementary control with current and voltage detection.It can adjust lights in a large range according to the requirements of light sources for various load characteristics（including resistive,inductive,capacitive） of the light source dimming control.It has less waveform distortion,high efficiency,fast dynamic response.It has a series of protection with high reliability.
