绝缘栅双极型晶体管(Insulated Gate Bipolar Transistor,简称IGBT)是一种结合金属氧化物半导体场效应晶体管(MOSFET)和双极结型晶体管(BJT)特性的复合型功率半导体器件。其核心结构包含三层半导体材料(N-P-N)和附加的P+层,通过栅极的绝缘层(通常为二氧化硅)实现电压控制。
该器件的工作原理基于电导调制效应:当栅极施加正向电压时,MOSFET部分导通,向N-漂移区注入载流子,显著降低导通电阻;关断时通过载流子复合快速恢复阻断状态。这种特性使其兼具MOSFET的高输入阻抗和BJT的低导通损耗优势。
在工业应用方面,IGBT广泛应用于:
根据国际电气电子工程师协会(IEEE)的测试数据,现代IGBT模块的开关频率可达150kHz,阻断电压超过6.5kV,工作温度范围扩展至-40℃至175℃。美国能源部的研究表明,采用IGBT的电力电子系统可将能源转换效率提升至98%以上。

绝缘栅双极型晶体管(Insulated Gate Bipolar Transistor,简称IGBT)是一种复合型功率半导体器件,以下是其术语的详细解释:
绝缘栅(Insulated Gate)
指器件的控制极(栅极)与主电路之间通过绝缘层(如二氧化硅)隔离。这种设计使控制信号与功率电路分离,兼具高输入阻抗和低驱动电流的特点。
双极(Bipolar)
指器件工作时同时利用电子和空穴两种载流子导电(类似双极型晶体管BJT),因此能承受高电压和大电流。
晶体管(Transistor)
广义指具有放大和开关功能的半导体器件。IGBT作为三端器件,包含集电极(C)、发射极(E)和栅极(G)。
IGBT结合了MOSFET的栅极控制特性和BJT的低导通损耗优势。其结构可看作由MOSFET驱动双极型晶体管的复合体:
特性 | MOSFET | BJT | IGBT |
---|---|---|---|
驱动方式 | 电压驱动 | 电流驱动 | 电压驱动 |
开关速度 | 快 | 慢 | 中高速 |
耐压能力 | 中低 | 高 | 高 |
导通损耗 | 高(压降大) | 低 | 低 |
适用场景 | 高频低功率 | 低频高功率 | 中高频高功率 |
IGBT凭借“绝缘栅控制+双极导电”的复合设计,成为现代电力电子系统的核心器件,平衡了效率、功率与成本。
