To make switching to the secondary server even easier, you can prepare the instance configuration and application definitions with the secondary server name, and then register the instance of notification services in advance 为了更轻松地切换到辅助服务器,可使用辅助服务器名称准备实例配置和应用程序定义,再预先注册notificationservices实例。
Its being used can form high efficiency insulated switching power supply without using utility power transformer . the switching power ic is selected firstly in the design of high power switching power supply, precision switching power supply, application specific switching power supply and so on in the world, which has been making switching power supply short, small, light and thin the control techniques of dc-dc switching converters are completely described and analyzed 单片开关电源管理集成电路具有高集成度、高性价比、简单外围电路、优越性能指标等优点,能构成高效率无工频变压器的隔离式开关电源,目前已成为国际上开发中、小功率开关电源、精密开关电源、专用开关电源以及开关电源模块的优选集成电路,使得开关电源正朝着短、小、轻、薄的方向发展。
"soft switching " is zero voltage switching or zero current switching, which the voltage ( or current ) of the switch varies by law of sine or quasi sine, the switch is on when its voltage reaches zero ( or switch is off when its current reaches zero ) by resonance . it makes switch loss is zero, so it can increase the operating frequency and raise power density, minimize the size of transformer and inductor “软开关”是指零电压开关或零电流开关,它是利用谐振原理,使开关变换器的开关管电压(或电流)按正弦(或准正弦)规律变化,当电压过零时,使器件开通(或电流自然过零时,使器件关断),实现开关损耗为零,从而提高开关频率,减小变压器、电感的体积。
