建立了某混合动力汽车控制器的热设计仿真分析模型，并通过温度测量试验验证了该模型的有效性。基于所建立的热设计模型，分析研究了控制器 PCB 板不同结构对其最大温升的影响程度。根据分析结果，推荐混合动力汽车控制器的 PCB 板应做成板厚为1.6 mm 的4层板，覆铜面积和1oz 的覆铜厚度应大于50%。

We build a thermal design simulation model for a hybrid vehicle controller, and verify validity of this model through temperature measurement test. Based on the thermal design model, we analyze and research the degree of influence of different structures of controller's PCB board on the maximum temperature rise. According to the analysis result, four layers of 1.6mm board thickness, more than 50 % coverage area percentage and 1oz copper coverage thickness are recommended for a better thermal design performance of the hybrid vehicle controller.
