The project will develop a novel miniature pulse width modulated power driver for actuators, I.E. Dc motor. The power driver will deliver 50 at 50vdo in a double inon package. This compact design can only be achieved through the innovative combination of modern power semiconductor technologies, proprietary circuit design, and state-of-the-art packaging technology which utilizes new heat conductive potting materials. The research will provide tools to accurately predict the total circuit efficiency for deferent types of suitable power semiconductors. The circuit designs will be analyzed with CAE technology to prevent internal device stresses due to incorrect pre-drive signals and thermal stress in the junction areas. A full feature proof of concept prototype will result from this analysis, including verification of final package size and budgetary price information.

The project will continue development with state of the art miniature servo amplifier. Three implementations will be performed and compared: surface mount technology (SMT) projected 0.8 cubic inches; hybrid technology expected volume 0.55 cubic inches: and "smart power" integration expected volume 0.4 cubic inches. The development will focus ont eh application of liquid cooling technology to achieve ultra high power densities. The devices will incorporate innovative minimum component count circuit technology, which has been successfully developed and tested during phase one of this project. The project will attempt to integrate the servo amplifier into the actuator. This will significantly reduce the required number of interconnects, and improve the systems reliability, noise and radiated energy output. Finally, integrated feedback sensors and an intelligent peripheral.
