目前电源技术的发展趋势为高频、高效、高密度化、低压、大电流化和多元化。准谐振模式转换器因其低电磁干扰特性及高效率特性可用于反馈开关模式电源的设计，尤其适用于电视中高频信号的处理，能起到低电流、过电压、过负载保护的功能，并有动态自供电(DSS)、准谐振工作、跳跃周期工作、过压保护、过载及短路保护等优点。采用NCPl207型控制器，以准方波共振模式运行的火控电源，可以降低回扫开关电源的电磁干扰，同时提高其功效，给出了空载运行模型进行仿真。

Now the development of the power supply trends were high frequency, high efficient, high definition, low pressure and big electric current with diversification. The quasi-resonant converters, with low electromagnetism interference and high-efficiency characteristics, could be used for the design of power supply of fly-back switch mode. It was particularly applicable to the handling of high frequency signal of Fire Control, and had the low electric current, conduct electricity to press, over load the aegis's functions, also had some advantages, such as DSS, quasiresonant the work, jump up the period work, over press to protec, over carry and short-circuit to protect. Electro-magnetic interference signature and improve efficiency were reduced by Fire Control power supply operating in quasi-square wave resonant mode using the NCPl207 control er. Lost motion model was given and simulated.
