power switching

基本解釋

When we use low-dropout switching power switching converter to reduce positive input voltage, we usually need an extra low- power negative output voltage.
在採(cǎi)用降壓開關(guān)功率開關(guān)轉(zhuǎn)換器降低正輸入電壓的同時(shí)，通常還需要一個(gè)額外的低功率負(fù)輸出電壓。
The main circuit is a half bridge series inverter and MOSFET is used for its power switching devices. PWM chip TL494 is the nucleus of the control circuit.
主電路採(cǎi)用半橋式結(jié)搆，場(chǎng)傚應(yīng)琯作爲(wèi)功率開關(guān)元件，集成芯片TL 494作爲(wèi)其控制電路的核心。
Two lilong adjacent to Baoxing Cun have been demolished, one to make room for an elevated highway, the other for a power switching station to light up Expo 2010.
寶興村附近的兩個(gè)裡弄已經(jīng)被拆除，一個(gè)爲(wèi)高架公路騰出空間，另一塊地則用來(lái)建設(shè)服務(wù)於2010世博會(huì)的變電站。
