Additive manufacturing technology for power electronics applications

In recent years, some high power density air-cooled power modules / inverters using WBG devices have been demonstrated for several power electronics applications. In addition to module packaging structure, power electronics converter packaging introduces another level of complexity to design a high density inverter/converters. 3D power electronics converter packaging with integrated interconnects and heat exchangers can reduce the required assembly steps and increase the power density of the whole system. Recent advancements in additive manufacturing (AM) promise an exciting future trend for more advanced power module / converter packaging technology to make inroads into the power electronics industry. AM techniques enable the development of complex 3D geometries that will result in size, volume, and material reductions at both component and system levels.
