摘要： A power system includes a traction battery, and a rectifier including a pair of diodes, a pair of switches, and a pair of capacitors each in parallel with a different one of the switches such that alternating current input to the rectifier results in alternating voltage having parabolic approaches to maximum magnitude values being input to the rectifier. The maximum magnitude values correspond to a magnitude of voltage output to the traction battery.

摘要： A method includes measuring an impedance of a shunt as a function of frequency and converting the impedance to an admittance in a time domain. The method further includes connecting the shunt in a circuit and measuring voltage data across the shunt over a predetermined interval. The method includes outputting a signal indicative of a current through the shunt derived from the voltage data convolved with the admittance. The method may be implemented in a controller configured to interface with the shunt.

摘要： A differential voltage probe for providing accurate measurement of differential voltage with high frequency components is disclosed that is further configured to accurately identify noise sources in EMI/EMC applications. The differential voltage probe is configured to provide the benefits of adequate differential voltage measurement bandwidth, galvanic isolation capability, high CMRR, flexible design to accommodate various requirements on voltage rating, loading effect, and frequency range of interest; and/or easy implementation and low cost. The differential voltage probe is able to achieve these optimized capabilities by implementing unique winding designs for transformer(s) used in the differential voltage probe circuit design.

摘要： A cooling system for a vehicular fuel cell utilizes packet pumps to electrically isolate the fuel from a grounded radiator. Fluid in a packet pump is transported from an inlet port to an outlet port in discrete packets. Because these packets are physically separated from one another, electricity does not flow through the fluid from the inlet port to the outlet port. Packet pumps include peristaltic pumps and external gear pumps.

摘要： 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.

摘要： Systems, apparatus and methods for cancelling a noise voltage at a vehicle are presented. An noise cancellation system (NCS) can be configured to null an earth-to-body voltage at the vehicle to prevent its interference with a receiver system. An (NCS) can include a noise sensor (NSSR) configured to sense a noise voltage, and a noise-nulling device (NNDV) configured to provide an anti-noise output. An anti-noise injector (ANI) can be configured to drive the anti-noise output at an anti-noise injection site In an example embodiment, an anti-noise output can be provided directly to the receiver system by cable. Alternatively, an anti-noise signal can be inductively or capacitively coupled to a vehicle structure or component that is not part of the receiver system. A noise cancellation system can be arranged in a feedback or feed-forward arrangement. Radio frequency noise and non-radio frequency noise can be cancelled.
