摘　　要：无极灯是一种新型的节能电光源,主要由高频发生器、耦合器和泡体构成,其中高频发生器的稳定工作对于无极灯来说具有重要意义,而高频发生器当中谐振电路参数的匹配好坏直接影响到无极灯能否正常点亮且能稳定工作。文中主要研究高频发生器当中谐振电路的工作状态以及谐振参数发生变化时谐振点如何偏移。首先对谐振电路进行阻抗分析;然后建立数学模型,通过MATLAB仿真得出谐振曲线;最后分析了无极灯稳定工作和启动阶段谐振参数的变化对谐振电路频域特性的影响。Electrodeless lamp is a new type of energy‐saving electric light source ,mainly consists of high frequency gener‐ator ,coupler and soaked body ,of which the stability of the high frequency generator work is of great significance for en‐ergy‐saving lamps ,and resonant circuit parameters of high frequency generator matching good or bad will directly affect the electrodeless lamp can light up normal and stable work .In this paper ,we study the resonance circuit of high frequen‐cy generator working condition and the resonant point how to offset when the resonance parameter changes .First ,analy‐sis the impedance characteristics of resonant circuit ,then set up the mathematical model ,and obtain the resonance curves through MATLAB .Finally analysis how the change parameter affect the frequency domain feature when electrodeless lamp stable work and start‐up phase .
