Abstract：针对变频空调用功率因数校正（PFC）电路中的电感在运行时存在局部过 热、温升较高的情况，本文采用电磁热耦合仿真对其进行了优化设计。通过有限元分 析，搭建了 PFC 电感三维电磁热场的仿真模型，利用电磁仿真计算得出 PFC 电感的 功率损耗，并将其作为热源进行了热场模拟。通过改变绕组的匝数和磁心的尺寸，模 拟了四组不同的设计方案，分别进行了磁场 - 热耦合分析，从中给出了优化设计方案。 实际运行表明，优化后的 PFC 电感有效降低了温升和损耗，设计方法对于其他电感器 件的设计具有参考价值。

Abstract： In view of the local overheating and the higher temperature rise of the inductance in the power factor correction (PFC) circuit of the inverter air conditioner during operation, the electromagnetic coupling simulation is adopted to optimize the design of the inductor. The three-dimensional electromagnetic thermal field simulation model of PFC inductor is established by the finite element analysis method. The power loss of each component of the reactor is calculated by electromagnetic simulation, and the thermal field is simulated as a heat source. By changing the number of turns and the size of the magnetic core, four different design schemes are simulated. The magnetic field thermal coupling analysis is carried out, and the optimal design scheme is given. The actual operation shows that the optimized PFC inductor effectively reduces the temperature rise and loss, and the design method is of reference value for the design of other inductors.
