The demonstration used a Porsche Taycan and was conducted in collaboration with Volkswagen Group of America using the ORNL-developed polyphase wireless charging system. The achievement surpasses ...

ORNL’s Omer Onar, left, power electronics research lead, discusses the 270-kW wireless charging system’s lightweight polyphase electromagnetic coupling coil, pictured in foreground ...

Also the polyphase induction motor is no longer to retain the great disadvantage in the matter of speed regulation, which makes it inferior to the continuous-current shunt motor, for successful ...

Recently, scientists at Oak Ridge National Laboratory in Tennessee conducted the first wireless power transfer to a Porsche Taycan, using a polyphase wireless charging system at 270 kW.

This often requires custom multi-tap polyphase scaling algorithms. FPGAs with an array of high-performance DSP structures are ideally suited for such algorithms, and FPGA vendors are beginning to ...

In November and December of 1887, Tesla filed for seven U.S. patents in the field of polyphase AC motors and power transmission. These comprised a complete system of generators, transformers ...

The system uses a pair of polyphase electromagnetic coupling coils about 50 cm (19″) wide to transfer the power over a gap of approximately 13 cm (5″). Efficiency is stated at 95%, and that ...

This 14-inch wireless charging device works at a rate of 100 kW, scientists claim, meaning it's up to 10 times as fast as some of the best commercially available alternatives. When you purchase ...

Texas Instruments has announced the MSP430F677x family of integrated metering SoCs comprising 60 devices designed to offer improved performance and anti-tampering protection for polyphase energy ...

Polyphase motors: Polyphase squirrel-cage motors are basically constant-speed machines, but some degree of flexibility in operating characteristics results from modifying the rotor slot design.
