THE DESIGN AND FABRICATION OF HYBRID CIRCUIT POWER SWITCHES INCLUDING DRIVE AND PROTECTION NETWORKS

THIS PROPOSAL WOULD ENCOMPASS THE DESIGN AND FABRICATION OF SOLID STATE POWER SWITCHES AS HYBRID CIRCUITS. THE CIRCUITS WOULD CONTAIN PARALLEL OUTPUT TRANSISTORS, ALL REQUIRED CURRENT DRIVE STAGES, HIGHTEMPERATURE AND HIGH-CURRENT PROTECTION. TEMPERATURES ARE MEASURED WITH SCREEN PRINTED OR CHIP THERMISTORS AND CURRENT WILL BE MONITORED AS A VOLTAGE ACROSS A SENSE RESISTOR OR OTHER METHOD YET TO BE DESIGNED, SUCH AS HALL-EFFECT SENSORS. ALL COMPONENTS WILL BE SCREEN PRINTED OR SURFACE MOUNT DEVICES, INCLUDING THE OUTPUT TRANSISTORS. SUCCESSFUL COMPLETION OF THIS ACTIVITY WILL RESULT IN THE FABRICATION OF A NUMBER OF WORKING CIRCUITS.
