Power Electronics Application and Integration • Advanced Power Devices • HVDC • FACTS • Custom Power • Integration of Small Generation
A Perfect Power Electronics Switch • Turn on and off instantaneously on command • Zero switching losses • Zero conduction losses • Zero gate power requirements (accept digital signal for turn-on turn-off) • Reasonable voltage and current capability • Can be connected in series and parallel to achieve higher switch ratings • Light weight • Sustain reasonably high ambient temperatures • Programmable to serve multiple applications
G S D Pd/Ag/Au Pd/Ag/Au Pd/Ag/Au AlGaN GaN AlN I - Advanced Power Devices Reduce Losses and Raise Switching Frequency • Advanced Silicon Devices Low Losses; Fast Switching; Low Thermal Resistance; Bidirectional; Integration of Passives • Wide Band Gap Devices Silicon Carbide; Gallium Nitrite; Diamond SiC
High Voltage Direct Current Transmission (HVDC) • Integration of Wind Generation Farms in the Transmission Grid • 100MW to 500MW Farms • Obtaining Transmission ROW takes much longer than Building Wind Farms • Underground DC Transmission with Voltage Sourced Converters could have: Lower Cost Improved System Integration Much smaller Permit and Construction time Narain G.

Basic FACTS and Custom Power Concept Line Line Line Inject Voltage Inject Voltage Inject Current • May be active static switch or impedance, converter or a combination thereof. • When in shunt, cause current injection into the line, and when in series, causes voltage injection in series with the line.
