Research on the Thermal Resistance Testing Method for Domestic SiC Power Modules
To address the issue of inaccurate testing of thermal resistance in domestic SiC power modules,research has been conducted on online measurement of module thermal resistance using non switching electrical methods.This paper propose a module thermal resistance testing scheme,design and build a module thermal resistance testing platform,and combine the structural and process characteristics of the device to study and obtain a suitable thermal resistance testing method for the module,and two typical SiC power modules were selected for verification,verifying the accuracy of the test results.
