【摘要】：为了表征大功率绝缘栅双极型晶体管(IGBT)模块的瞬态热响应行为,设计并实现了一种基于电学法的IGBT模块瞬态热阻测试装置.通过改变热阻测试装置的加热脉冲持续时间,使其等于不同材料层的热时间常数,控制热流在IGBT模块封装材料中的有效传播路径,进而获得各封装材料的瞬态热阻.此外还具体分析了高低电平转换过程中暂态噪声和边界散热条件对测试结果精度的影响规律.结果表明,该装置具有较好的精确性和重复性,这将有助于准确无损分析器件及不同封装材料在瞬态条件下的散热性能,指导IGBT模块封装结构设计和封装材料选择.
[Abstract]:In order to characterize the transient thermal response behavior of high power insulated gate bipolar transistor (IGBT) module, a transient thermal resistance testing device for IGBT module based on electrical method is designed and implemented. By changing the duration of the heating pulse of the thermal resistance testing device and making it equal to the thermal time constant of different material layers, the effective path of heat flow in the IGBT module packaging material is controlled, and the transient thermal resistance of each package material is obtained. In addition, the influence of transient noise and boundary heat dissipation on the accuracy of the test results is analyzed in detail. The results show that the device has good accuracy and repeatability, which will be helpful to accurately and nondestructive analysis of the heat dissipation performance of devices and different packaging materials under transient conditions, and guide the design of IGBT module packaging structure and the selection of packaging materials.
