AVS10屬于分立半導(dǎo)體產(chǎn)品的晶閘管-TRIAC。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的AVS10晶閘管 - TRIAC晶閘管可沿一個(gè)方向或在半個(gè) AC 周期內(nèi)傳導(dǎo) AC（交流電）。當(dāng) TRIAC（三極管 AC）的門(mén)極被觸發(fā)時(shí)，即會(huì)沿任一方向傳導(dǎo)電流。其他名稱(chēng)包括雙向三極晶閘管或雙側(cè)三極晶閘管。TRIAC 分為無(wú)緩沖器、Alternistor、內(nèi)部觸發(fā)、邏輯門(mén)和標(biāo)準(zhǔn)型，安裝方式包括底座、表面或通孔安裝。這些器件可根據(jù)斷態(tài)電壓、通態(tài)電流、保持電流和門(mén)極觸發(fā)電壓進(jìn)行選擇。

DESCRIPTION

The AVS20 (AVS200) kit is an automatic mains selector (120/230V AC) to be used in SMPS with input power < 300 W. It is composed of 2 devices :

? The Controller is optimized for low consumption and high security triggering of the triac. When connected to VSS, the mode input activates an additional option “the latched option”. If the main power drops from 230V to 120V, the triac control remains locked to the 230V mode and avoids any high voltage spike when the voltage is restored to 230V. When connected to VDD, the mode input desactivates this option “this is the follower option”.

? The TRIAC is speciallydesigned forthis application. An optimization between sensitivity and dynamic parameters of the triac gate highly reduces the losses of supply resistor and allows excellent immunity against line disturbances.
