The Modeling and Simulation of High Pressure Sodium Lamp Electronic Ballast

高压钠灯(HPS)电子镇流器是1个非线性系统,多采用电路模型对其进行设计与分析。为了实现对高压钠灯电子镇流器的闭环控制,需建立其动态数学模型。文中在建立电子镇流器各单元数学模型基础上,综合出整机数学模型。Matlab\Simulink仿真与实际测量对比表明,本文建立的数学模型准确描述了高压钠灯电子镇流器运行状态,为闭环控制算法建立提供了依据。

High pressure sodium lamp （HPS） electronic ballast is a nonlinear system. The circuit model is used for the design and analysis. In order to achieve closed-loop control of electronic ballast for high pressure sodium lamps, a dynamic mathematical model needs to be established. Based on the units of the electronic ballast, machine mathematical model was integrated and established in this paper. Compared with actual measurements, Matlab／ Simulink simulation showed that the run state of the high pressure sodium lamp electronic ballast was accurately described in the mathematical model. It also provides the basis for the establishment of closed-loop control algorithm.
