摘要：本文在分析1GBT的動態(tài)開關(guān)特性和過流狀態(tài)下的電氣特性的基礎(chǔ)上，通過對常規(guī)的IGBT推挽驅(qū)動電路進(jìn)行改進(jìn)，得到了具有良好過流保護(hù)特性的IGBT驅(qū)動電路。該電路簡單，可靠，易用，配合DSP等控制芯片能達(dá)到很好的驅(qū)動效果Abstract：Based on the studies on the dynamic switching and over-current characteristics of IGBT，this paper makes some improvments to the original push-pull driving circuit，obtains a new IGBT driving circuit which has a good over-current protection function.The circuit is simple，reliable and easy to use.Combined with controlling chips such as DSP it will do a great job in driving applications.關(guān)鍵詞：IBGT：開關(guān)特性；驅(qū)動；過流保護(hù)；Key Words:IGBT；switching characteristics；driving:over-current protection
