Patent number: 7301755Abstract: Power converters such as power modules configured as inverters employ modularized approaches. In some aspects, semiconductor devices are thermally coupled directly to thermally conductive substrates without intervening dielectric or insulative structures. Additionally, or alternatively, semiconductor devices are thermally coupled to thermally conductive substrates with relatively large surface areas before heat transferred from the semiconductor devices encounters a dielectric or electrically insulating structure with correspondingly high thermal impedance.Type: GrantFiled: December 13, 2004Date of Patent: November 27, 2007Assignee: Siemens VDO Automotive CorporationInventors: Pablo Rodriguez, Douglas K.
