Current Projects: Seeking Business Partners & Qualified Investors
 

Sensor: Advanced Transistor Integral Current Sensor


(a) SiC-based transistor current sensor - rapidly detect over currents
(b) cost, mass, volume do not scale at higher power levels –
products

      today do scale cost, mass volume
(c) sensing time in ns, NOT μs, extremely low capacitance
(d) small, discrete device can be inside power modules
(e) can be integrated into power transistor


White Paper: ATICS Architecture, Benefits, Use Cases


Inverter: Lower Cost, Mass, Volume Inverter


(a) 5 kW prototype shows 95% conversion efficiency with a 220 Vac, single

      phase input
(b) 20 kW 480 Vac, 3 phase input module design – up to 50% cost,
mass,

       volume savings vs. legacy products
(c) potential to achieve 98% efficiency via known design
improvements
(d) major cost, mass, volume savings vs legacy architectures
(e) no need for large DC energy reservoir capacitor pool

 

White Paper: Advanced Converter, Power Factor Converter


Inductor: Modular, Scalable, Test & Measurement Inductor


(a) up to 3 kV@150 Amps or 6kV@75 Amps per module
(b) up to 10 modules per system, measure up to 60,000 V or 1,500 A
(c) test SiC semiconductors, power modules, power devices in R&D

      applications
(d) test SiC semiconductors, power modules, power devices in

      manufacturing applications
(e) measure switching speed, switching on & off loss energies, voltage,

      current, avalanche breakdown, & switching frequency of high voltage

      and/or high current semiconductors, power modules, power devices
