Abstract: A power module has upper and lower transistor dies carried by a lead frame assembly. The assembly has a positive DC paddle for the upper die and an AC paddle for the lower die. An upper plate interconnects a second side of the upper die with the AC paddle, and a lower plate interconnects a second side of the lower die with a negative power bar. Current flowing via positive and negative power bars defines a power loop creating a main magnetic flux with a first direction in a central region and a return direction outside the central region. The upper and lower plates have outer edges having respective notches to concentrate respective portions of a return magnetic flux. Each die has a gate pad connected in a gate loop, wherein the gate loops each overlap a respective concentrated return flux thereby enhancing a common source inductance for each transistor.

Abstract: A near field communication (NFC) reader module is provided for mounting over a metal panel of a vehicle. A housing of the module is configured to mount adjacent the metal panel. The housing contains a planar array of non-magnetic RF filter elements in the housing proximate to the metal panel. The housing contains a planar antenna coil configured to couple with an external NFC device carried by a user, wherein the array of RF filter elements is disposed between the planar antenna coil and the metal panel to magnetically decouple the planar antenna coil from the metal panel. The housing further contains receiver circuitry configured to decode NFC signals from the external NFC device.

Abstract: A wireless power transfer system has a coil assembly including a ferrite pad and a pair of spaced apart inductive coils on the ferrite pad, and a switching network that, in response to an indication of a corresponding inductive coil assembly configuration, controls a direction of current flow through each of the coils to selectively operate the coils in a two-pole mode or a three-pole mode.

Abstract: A wireless power transfer system includes a coil assembly including a pair of spaced apart inductive coils positioned on a same side of a ferrite pad, and a switching network. The switching network, in response to an indication of a corresponding inductive coil assembly configuration, selectively operates the coils in a two-pole mode or a three-pole mode.

Abstract: A secondary side wireless power transfer compensation circuit includes a secondary coil, a capacitor in series with the secondary coil, and an inductor in parallel with the secondary coil and capacitor. The inductor has an impedance matching a reflected impedance of a load electrically connected thereacross such that the secondary coil achieves resonance with a primary coil coupled therewith at a predetermined frequency that depends on the impedance.

Abstract: A vehicle includes an inductive charge coupling arrangement that can be electrically connected with a traction battery. The arrangement includes a charge coil and a plurality of permeable panels surrounding the charge coil. The vehicle further includes at least one controller that, in response to an inductive charge request, causes the panels to move to positions selected to minimize electromagnetic field leakage between the charge coil and a charge station.

Abstract: A wireless vehicle charging system includes at least one controller configured to operate an inverter to control a voltage input to a power converter in a vehicle to drive an impedance phase angle at an output of the inverter toward a predetermined angle and achieve a power demand at an output of the vehicle power converter. The at least one controller is further configured to operate the vehicle power converter to achieve the power demand. The at least one controller may control a frequency output of the inverter to adjust the voltage input to the power converter based on a rate of change of an objective function that is configured to reduce an output power error of the power converter and an impedance phase angle error at the output of the inverter.
