Abstract

This work focuses on technical barriers to the implementation of controllers for auxiliary electric motors for automotive applications. It addresses the integration of three-phase brushless DC motors and advanced microelectronic packaging techniques into compact motor controllers. The proposed packaging techniques are focused on thermal performance utilizing minimum supplemental cooling. The primary focus of this discussion is the reduction of thermal resistance by the elimination of interfaces between the power devices and the heat sink. The initial application of this work is targeted at variable speed compressors for 42 V vehicles.
