Profile Summary

Co-Director of WEMPEC with 90 international sponsors, long term research leadership, now celebrating its 35th anniverary

Pioneer in self-sensing control of electric machines using rotating and pulsating vector injection methods, including design of electric machines for robust self-sensing,

Pioneer in deadbeat control of torque and flux for electric motor drives achieving the fastest possible torque dynamic while simultaneously and independently controlling flux manipulation for loss manipulation and injection based self-sensing with no torque ripple,

Pioneer in design and control of variable leakage flux - and variable magnetization state - electric machines to enable dynamic loss minimizing control,

Pioneer in integration of point field detector arrays in power electronic modules for ultra high bandwidth, galvanically isolated, non-invasive current sensing.

Pioneer in high bandwidth, non-invasive, power semiconductor junction temperature estimation using device temperature sensitive properties,         

Pioneer in dynamic ∆Tj control to actively regulate the power cycling thermal stress in power semiconductors to achieve lifetime control.

Pioneer in measurement of strain in actively switched power semiconductors, both in the semiconductor material and in the wire bond and lead frame die interconnect.

Pioneer in high efficiency coil design for MHz frequency wireless power transfer over sub-meter gaps with flux levels in the air gap that are inherently safe.
