Eaton, working with NETL and NCSU, will develop high-power density SiC-based wireless power AC-DC converter technologies. Such technologies can convert power from medium voltage to DC output voltage for distribution system applications requiring ease of service, safety, efficiency, and power density.
An isolated wireless power link enables medium voltage distribution directly to the point of use, safely stepping the voltage down to application levels without exposing the application hardware and end user to the dangers of the proximity of medium voltage and hazardous arc-flash. Operating the converter in resonant mode minimizes harmonics, reduces EMI due to the sinusoidal output waveform, and prevents faults on the secondary side from cascading to the medium voltage bus (a fault will cause a loss of resonance and disrupt power flow). This technology will enable simplification of the distribution system by eliminating a transformer and reducing the distribution current level, which will reduce the use of copper, leading to reduced system cost and improved system efficiency
