Abstract

This paper presents a reliability study on a Microsemi 5 kVA Integrated Power Solutions (IPS) module designed to drive an electrical motor in a More Electric Aircraft actuation system. The measures taken in the design of the product and the reliability advantages of incorporating silicon-carbide MOSFETs as an alternative to silicon IGBTs are detailed. The MTBF of the unit is presented and a laboratory test setup for verifying the results is outlined.
