Abstract
Transportation electrification in many forms along with continued grid modernization efforts are placing stringent requirements on volumetric and gravimetric power densities for power electronic converters, motor drives, and protection systems. These requirements flow down to more stringent specifications on power module packages that typically comprise these systems. For instance, the PowerAmerica (PA) Institute issued a module challenge in 2021 to develop a 1.7 kV / 1600 A power module within a volume of 100 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> during case of one year. This paper describes, in tutorial fashion, how to approach the design and realization of such an aggressive module. It begins from an overview of an application-driven development process of prototypes for power module, including design, fabrication, and evaluation. Then, the PA module is used as a development example to illustrate the detailed challenges faced in the multi-dimensional design space and explore the technologies and strategies for high-power high-density module realization. Consequently, the knowledge involved can be transferred and facilitate the prototype development of new power modules.
