Briefly introduce the former study of chaos and the common method of chaos modeling . ( 2 ) some discrete - time maps based on different switching mode are summarized and analytical expressions suitable for general dc / dc converters are present ( 2 )对几种基于不同切换方式的离散映射进行归纳总结,得到适合一般dc / dc变换器精确建模的解析表达式,同时总结了混沌现象研究的常用工具。
The development of microprocessor provides a new method for switching mode power supply control - digital control . digital control has many advantages such as repeatability , durability , adaptability and so on 微电子集成技术的发展为电力电子控制技术提供了新的思路,由六十年代的分立元件发展到后来的集成电路、大规模集成电路、微处理器等,为功率变换的控制带来了极大的方便。
The unilateral control strategies can be classified into two basic control modes : un - alternate switching mode and synchronous rectification ( sr ) mode . the theoretical analysis and simulations of these two control modes were given in detail , also with the experimental verification 对单边控制策略下的两种控制模式:非互补导通和互补导通即同步整流控制,分别进行了深入的理论和仿真分析及实验验证。
The mgcph . 248 end mode in soft switching and the pure sip mode will be more suitable for the application of ip metropolitan area network of the lan access ; while the big media gateway of the soft switching mode will more suitable to replace the existing local or circuit switch ( packet switch ) 软交换中mgcph . 248终端方式和纯sip方式更适应在lan接入的宽带ip城域网上开放;软交换中大媒体网关的方式更适应替代现有的本地或长途电路交换机。
switching mode meaning:[Electronics] Operation in which a device, such as a transistor or diode functions as a binary digital device, rather than as an analog device. The current is generally either zero (cutoff or pinchoff...switching mode перевод:1. вид переключения 2. режим переключения; режим коммутации 3. режим импульсного преобразования (в источниках питания)
