Self-sensing as an integration focus for motor drives and power devices

Self-sensing (sensorless or fully integrated sensing) methods in motor drives and power devices is a major opportunity to extend the early generations of fully integrated sensing to become central to the next generation of motor drive and power device design. To achieve the next level of integration, solutions that cross technology boundaries and are intrinsically multi-functional will be required, whereby the design-for-self- sensing in all actively controlled devices will be the norm. This paper and presentation will focus on the critical elements of the new multi-disciplinary self-sensing paradigm as it applies to both machine and power devices used in motor drives and all forms of power conversion equipment.
