| 摘要: |
| 绝缘栅双极晶体管(IGBT)的并联运行能够承受更高的负载电流，但同时也带来了动、静态的均流问题．从理论上分析认为导致动、静态不均流的主要因素是器件的饱和导通压降Uce(sat)不同引起的。提出了IGBT并联均流的措施，指出了构建IGBT并联电路的要点，以及应用栅极电阻补偿法进行均流，仿真分析验证了提出的方法措施可行。 |

| Abstract: |
| IGBTs(Insulated Gate Bipolar Transistors) operating in parallel,which endure heavier load currents,bring the problem of static and dynamic current balancing. It is concluded theoreti,cally that the different Uc e(sat)(voltage drop during saturation conduction) is the main factor causing un,balanced currents. Some countermeasures are put forward:such as essentials for constructing IGBT parallel circuit,the gate resistance compensation and so on. Simulation proves its feasibility. |
| Key words: IGBT,parallel connection,current balancing, |
