| 摘 要： | 为了电子镇流器电路的准确分析和设计，对半桥逆变电路的稳态工作状态进行了时域分析，把工作在高频状态下的灯管近似等效为一个电阻，运用分阶段时域分析法推导大功率细灯管节能灯的灯管电压表达式，并用示波器测量出灯管两端电压波形，结果显示，实测波形与理论波形基本一致，为电子镇流器的设计工作提供了依据和便利，具有较大的应用价值。

| Abstract: | In order to analyze and design electronic ballast correctly,the paper make time domain analysis of stable function of half-bridge inverter.By considering the discharge lamp as a resistor in steady state and using time domain analysis methods,we derive voltage expression of high power energy conservation lamp with thin tube in detail,and measure the voltage wave in the two ends of tube with help of oscilloscope.The result shows that the measured wave is basically consistent with that in theory,which serves as a foundation for the design of electronic ballast,and is the great practical application. |
