Extracting the junction temperature of an insulate-gate bipolar transistor (IGBT) module is an essential part for its health monitoring and lifetime evaluation. The commonly used open-loop observer suffers from a lack of disturbance rejection capability, while the closed-loop scheme is infeasible since the states of a heat transfer system are not completely observable. Therefore, a composite observer suitable for online IGBT junction temperature extraction is proposed, where a closed-loop part is built therein via the observable states and the residual unobservable states construct an open-loop part. Aimed at an H-bridge inverter constructed with FF225R12ME4 IGBT chip, the design procedure of the composite observer is given in detail. Finally, real-time simulations of the composite observer were conducted on a hardware-in-loop (HiL) system, i.e., dSPACE DS1202. The HiL simulation results verified the superiority of the proposed composite observer in suppressing the effect of loss calculation errors on the estimation accuracy over the conventional open-loop observer.

绝缘栅双极型晶体管IGBT（insulate-gate bipolar transistor）模块的结温提取是其健康监测和寿命评估的一个重要环节。常用的开环观测器缺乏抗干扰能力，闭环方案则由于传热系统的状态不完全能观而不可行。因此，提出了1种适用于IGBT结温在线提取的复合观测器，其闭环部分通过能观状态构建，其余不能观状态则构成开环部分。针对以FF225R12ME4型号IGBT为器件的H桥逆变器，给出了IGBT结温复合观测器的详细设计过程。最后，在硬件在环HiL（hardware-in-loop）系统dSPACE DS1202上对该复合观测器进行了实时仿真验证。HiL仿真结果验证了所提出的复合观测器在抑制损耗计算误差对估计精度的影响方面优于传统的开环观测器。
