超音頻電源IGBT驅(qū)動脈沖重合時間的控制
本文共4頁 1972字
摘要：IGBT并聯(lián)式逆變超音頻感應(yīng)加熱電源負(fù)載適應(yīng)性強(qiáng)，頻率可達(dá)70kHz，功率可達(dá)幾百千瓦，現(xiàn)已在很多場合取代了SCR中頻電源，廣泛應(yīng)用在感應(yīng)加熱領(lǐng)域。主要簡述了IGBT并聯(lián)式逆變器的工作原理。IGBT驅(qū)動脈沖重合時間的控制，以及重合時間不足或太長所引發(fā)的問題。
關(guān)鍵詞：感應(yīng)加熱，電源，驅(qū)動／超音頻電源
Abstract：Ultra—audio induction—heating power supply based on IGBT parallel inverter can adapt to variable load，whose frequency range can come up to 70kHz and the power Can reach several hundreds kilowatt．At present it substitutes for SCR intermediate frequency power supply and can be applied to many fields especially induction—heating industry．The article mostly describes the working principle of the IGBT parallel inverter，the superposition time control of the pulse which can drive IGBT for working and the problem due to the overlong superposition time or insufficiency one．
Keywords：induction heating；power supply；drive／ultra—audio power supply
