摘要
本文通过对电压型半桥准谐振电子镇流器高频逆变电路的频域分析,根据电网及负载情况,采用基波近似方法,对谐振逆变电路稳态工作的最佳工作点选取方法进行了研究。同时分析了输入电网变化对逆变电路稳态工作点及电子镇流器性能和可靠性的影响。最后给出了一个电子镇流器的设计实例。
A frequency domain analysis is given for a voltage fed half bridge quasi resonant electronic ballast.According to parameters of the resonant inverter and the input ac line,using the fundamental component approximation techniques to choise the better operation point are discussed.In addition,for strike lamp,the lowest rate of operation frequency to the corner frequency of resonant circuit has been shown.
