摘　　要：本文介绍了一种新型HPS舞台灯的控制设计,分析了高压钠灯PWM逆变电路的基本结构和HPS舞台灯闪烁变化的基本原理,推导出驱动频率和功率之间的关系。结合控制电路的设计,讨论了电路所能实现的功能,并进行运行测试。实验表明,设计电路能够通过控制电压调节频率,并能够按照舞台灯的变化要求调节HPS灯的功率,实现舞台灯闪烁变化的多种效果。This paper presents a novel control design of stage lighting with HPS lamp. The relationship between drive frequency and light power are deduced by analysing the basic structure of PWM inverter for high pressure sodium lamp and the flicking principle of stage lighting with HPS lamp. Combined wilh the schematic design diagram of control circuit, the functions that the circuit would realize are discussed and the experiment has been operated.
