Abstract: Exemplary embodiments of the present invention relate to a power line communication (PLC) system. For example, the PLC system may include a PLC server configured to provide electrical power and electronic communications through a PLC bus to a number of electronic devices, such as an instrument cluster, infotainment interface, rear-seat entertainment console, aftermarket accessories, and the like. The PLC system may also include a power system that may be coupled to an electrical grid for charging a battery associated with one or more of the electronic devices. The power system may be communicatively coupled to the PLC bus, enabling the devices coupled to the PLC bus to communicate with a service provider through the electrical grid. The communications between the devices coupled to the PLC bus and remote devices coupled through the electrical grid may be conducted using a common communication protocol.

Abstract: Described herein are improved configurations for a wireless power converter that includes at least one receiving magnetic resonator configured to capture electrical energy received wirelessly through a first oscillating magnetic field characterized by a first plurality of parameters, and at least one transferring magnetic resonator configured to generate a second oscillating magnetic field characterized by a second plurality of parameters different from the first plurality of parameters, wherein the electrical energy from the at least one receiving magnetic resonator is used to energize the at least one transferring magnetic resonator to generate the second oscillating magnetic field.

Abstract: A controlling apparatus for a motor vehicle has a high voltage direct current (dc) power supply, an inverter for converting dc power of the high voltage dc power supply into ac power, a smoothing capacitor provided between the inverter and the high voltage dc power supply, a main contactor provided between the high voltage dc power supply and the smoothing capacitor for connecting and disconnecting the high voltage dc power supply and the smoothing capacitor to and from each other, and a precharge circuit connected in parallel to the main contactor.

Abstract: A backup power supply system supplies power from a first ac power source in normal condition. Once the first ac power source is abnormal or fails, the system automatically turns off the first ac power source and turns on a second ac power source with null transfer time. When the first ac power source is normal, a dc/ac power inverter is controlled to supply an approximately null current such that a mechanical switch is allowed to be closed and no circulating current is generated between the first ac power source and the dc/ac power inverter. Since the mechanical switch is continuously closed, and requires no switching operation, the backup power supply system can supply the backup power with a null transfer time.

Abstract: According to one embodiment, an integrated circuit is disclosed. The integrated circuit includes a plurality of circuit blocks. Each circuit block includes a voltage differentiator that generates a local supply for the circuit block.

Abstract: A method and system for connecting a plurality of power generators, each having an electrical power converter output and adjustable output voltage magnitude and frequency, with at least one digital communications bus to provide synchronization and load sharing. One of the plurality of power generators is designated a master unit and the remainder are designated as slave units.
