Abstract: A dual dynamic wireless charging system for battery-dominant vehicles is provided, including for example battery electric vehicles (BEVs), fuel cell electric vehicles (FCEVs), and hybrid-electric vehicles (HEVs). The dynamic wireless charging system includes a transmitter coil installed on a transmitter vehicle, the transmitter coil being inductively coupled to a receiver coil installed on a receiver vehicle. Power transfer is achieved wirelessly while both vehicles are in motion, such that the receiver vehicle does not come off-mission. The transmitter vehicle and the receiver vehicle can travel in a side-by-side configuration, being parallel to each other in adjacent lanes. In other embodiments, a lead-and-follow configuration is used in place of a side-by-side configuration. Vehicle-to-vehicle communications ensure rapid adjustments to speed and trajectory, allowing seamless alignment despite variations in roadway conditions and traffic.

Abstract: A system and method for generating a heat sink for circuitry, such as a power module, that facilitates removal of heat from the circuitry. To improve power density of power modules, not only electrical but also thermal optimization may be carried out as the two subsystems closely interact with each other.

Abstract: A system and method for generating a heat sink in multiple dimensions for circuitry, such as a power module, that facilitates removal of heat from the circuitry. To improve power density of power modules, not only electrical but also thermal optimization may be carried out by merging multiple reference sections or anchor planes, each of which may be determined according to a Fourier transform.

Abstract: A capacitor packaging having a central termination and three or more capacitors (or groups of capacitors) arranged about the central termination. The electrical flow paths between the termination and the capacitors or groups of capacitors are of substantially the same length. The capacitors or groups of capacitors may be arranged in a generally circular pattern with the termination centered on the center. The termination may include first and second terminals. The capacitors may be mounted to a printed circuit board (“PCB”) with traces on opposite surfaces of the PCB providing electrical flow paths from the terminals to opposite legs of the capacitors. The capacitor packaging may include a primary PCB with a first circular arrangement of capacitors and a secondary PCB with a second circular arrangement of capacitors. The capacitors may be sandwiched between the PCBs with the second arrangement of capacitors disposed concentrically inwardly of the first arrangement.
