IGF::OT::IGF THE GOAL OF THE PHASE I EFFORT IS TO DESIGN, DEVELOP AND DEMONSTRATE A NOVEL SOLID-STATE CERAMIC-BASED VOLTAGE ISOLATOR AND DEMONSTRATE ITS POTENTIAL TO PROVIDE A HIGHLY RADIATION TOLERANT DIGITAL VOLTAGE ISOLATION SOLUTION APPLICABLE TO A WIDE RANGE OF NASA MISSION REQUIREMENTS. THE RELATED DESIGN SUCCESS QORTEK HAS WILL LEAD TO DEVELOPMENT IN PHASE I OF A COMPLETELY NEW GATE DRIVE TECHNOLOGY WITH MANY ADVANTAGES AND BENEFITS TO THE ENTIRE SPECTRUM OF NASA AND COMMERCIAL APPLICATIONS. THE PHASE I DESIGN GOALS ARE FOCUSED PRIMARILY ON EARLY COMSOL MULTIPHYSICS BASED FINITE ELEMENT ANALYSIS (FEA) OF THE PROPOSED CERAMIC DEVICE, AS WELL AS ELECTRICAL CIRCUIT DESIGN AND SPICE MODELING OF A HIGH-SIDE MOSFET GATE DRIVER SYSTEM INCORPORATING THE NEW CERAMIC ISOLATOR. THIS PRELIMINARY DEVELOPMENT EARLY IN THE PROGRAM WILL ENABLE THE MAIN OBJECTIVE OF PHASE I WHICH IS TO FABRICATE INITIAL ISOLATOR CERAMIC-BASED GATE DRIVER PROTOTYPES AND UNDERTAKE BASIC ELECTRICAL TEST CHARACTERIZATION OF THEIR PERFORMANCE. AN ALL-INCLUSIVE ELECTRICAL DESIGN TARGETED TO ISOLATED MOSFET GATE DRIVER APPLICATIONS WILL ALSO BE DEVELOPED AS A FUNCTIONAL DEMONSTRATION PLATFORM PROTOTYPE. THE PURPOSE OF THE PHASE I PROTOTYPES IS TO DEMONSTRATE, THROUGH HARDWARE FUNCTIONAL TESTING AND DEVICE CHARACTERIZATION, THAT THE CERAMIC GATE DRIVER TECHNOLOGY PROVIDES A FEASIBLE SIZE AND PERFORMANCE EQUIVALENT REPLACEMENT FOR SIMILAR COTS NON-RAD HARD ISOLATION SOLUTIONS.
