Summary on Grant Application Form |
|
The programme aims to demonstrate a novel, vertical power FET with integrated intelligent gate drive circuitry based on gallium arsenide technology. Theoretical benefits include an 8.5 times increase in maximum operating frequency and reduced on-state losses. Projected voltage and current ratings of 800V and 10A respectively will allow realistic comparison with silicon devices operating in off-line applications at power levels up to 1kW. A first generation structure will demonstrate the power device and logic level devices on a single die using SERC facilities at Surrey. Subsequent structures will incorporate further logic level devices to realise the integrated, intelligent drivers. Two such FETs will be employed in a resonant half-bridge circuit operating in an off-line environment at frequencies up to 30mhz. CAE techniques will be used extensively as part of the design and analysis procedure and a theoretical study of other vertical gallium arsenide structures, together with a study of their suitability for power applications, will be undertaken.
