絕緣栅雙極型晶體管(Insulated Gate Bipolar Transistor,簡稱IGBT)是一種結合金屬氧化物半導體場效應晶體管(MOSFET)和雙極結型晶體管(BJT)特性的複合型功率半導體器件。其核心結構包含三層半導體材料(N-P-N)和附加的P+層,通過栅極的絕緣層(通常為二氧化矽)實現電壓控制。
該器件的工作原理基于電導調制效應:當栅極施加正向電壓時,MOSFET部分導通,向N-漂移區注入載流子,顯著降低導通電阻;關斷時通過載流子複合快速恢複阻斷狀态。這種特性使其兼具MOSFET的高輸入阻抗和BJT的低導通損耗優勢。
在工業應用方面,IGBT廣泛應用于:
根據國際電氣電子工程師協會(IEEE)的測試數據,現代IGBT模塊的開關頻率可達150kHz,阻斷電壓超過6.5kV,工作溫度範圍擴展至-40℃至175℃。美國能源部的研究表明,采用IGBT的電力電子系統可将能源轉換效率提升至98%以上。

絕緣栅雙極型晶體管(Insulated Gate Bipolar Transistor,簡稱IGBT)是一種複合型功率半導體器件,以下是其術語的詳細解釋:
絕緣栅(Insulated Gate)
指器件的控制極(栅極)與主電路之間通過絕緣層(如二氧化矽)隔離。這種設計使控制信號與功率電路分離,兼具高輸入阻抗和低驅動電流的特點。
雙極(Bipolar)
指器件工作時同時利用電子和空穴兩種載流子導電(類似雙極型晶體管BJT),因此能承受高電壓和大電流。
晶體管(Transistor)
廣義指具有放大和開關功能的半導體器件。IGBT作為三端器件,包含集電極(C)、發射極(E)和栅極(G)。
IGBT結合了MOSFET的栅極控制特性和BJT的低導通損耗優勢。其結構可看作由MOSFET驅動雙極型晶體管的複合體:
特性 | MOSFET | BJT | IGBT |
---|---|---|---|
驅動方式 | 電壓驅動 | 電流驅動 | 電壓驅動 |
開關速度 | 快 | 慢 | 中高速 |
耐壓能力 | 中低 | 高 | 高 |
導通損耗 | 高(壓降大) | 低 | 低 |
適用場景 | 高頻低功率 | 低頻高功率 | 中高頻高功率 |
IGBT憑借“絕緣栅控制+雙極導電”的複合設計,成為現代電力電子系統的核心器件,平衡了效率、功率與成本。
