Technologies directed to a direct rotor current measurement for transformer-fed wound rotor machine are described.
Technologies are described that are directed to polyphase rotary transformer for field excitation of electric machines.
Distortion generated during additive manufacturing of metallic components affect the build as well as the baseplate geometries. These distortions are significant enough to disqualify components for functional purposes.
Technologies directed to an LCC based induction cooktop architecture for non-ferromagnetic pan are described.

For additive manufacturing of large-scale parts, significant distortion can result from residual stresses during deposition and cooling. This can result in part scraps if the final part geometry is not contained in the additively manufactured preform.
Output Current Estimation and Control in Primary Side LCC Secondary Side Series Compensated Wireless
Wireless charging of electric vehicles require the ability to control the output current in the power transfer system, but that is often not possible as the availability of signals from the secondary side to the primary side is difficult and not always feasible.
In additive manufacturing large stresses are induced in the build plate and part interface. A result of these stresses are deformations in the build plate and final component.
This invention presents a multiport converter (MPC) based power supply to charge the 12 V and 24 V auxiliary batteries in heavy duty (HD) fuel cell (FC) electric vehicle (EV) power train.
