HF POWER SUPPLY FOR SUBMARINE COMBAT SYSTEMS

RELIABLE AND CONTINUOUS POWER TO SUBMARINE ELECTRONICS IS ESSENTIALFOR MISSION EXECUTION AND FOR THE SAFE OPERATION OF THE SHIP. DIGITAL ELECTRONICS CANNOT CONTINUE OPERATION THROUGH EVEN VERY SHORT POWER OUTAGES CAUSE BY BUS TRANSFER DEVICES, THAT HAVE HISTORICALLY BEEN SUFFICIENT FOR ANALOG COMBAT SYSTEMS. THE RESTART AND RELOAD THAT A DIGITAL SYSTEM MUST EXECUTE AFTER A SHORT POWER INTERRUPTION AND THE SUBSEQUENT CONFUSION THAT RESULTS WHILE OPERATORS RECOVER THE TACTICAL PICTURE ARE A HAZARD TO THE SHIP. A CENTRAL, AUCTIONEERED DC POWERSYSTEM HAS BEEN PROPOSED TO PROVIDE UNINTERRUPTIBLE POWER. THIS SYSTEM IS HEAVY, COMPLEX, AND POTENTIALLY UNRELIABLE. AN ALTERNATIVE TOTHE DC SYSTEM IS PROPOSED. NEW MATERIALS ARE AVAILABLE THAT ALLOW A DOUBLING OF THE POWER DENSITY OF THE POWER SUPPLIES ON THE ELECTRONIC CABINETS. THE PROPOSED CONCEPT USES TWO AUCTIONEERED POWER SUPPLIES ON EACH DRAWER, EITHER OF WHICH CAN CARRY THE LOAD OF THE DRAWER.THE WORK PROPOSED TAKES AN EXISTING 1OO-WATT UNIT AND SCALES IT UP TO A FOUR-UNIT NETWORK WITH APPROXIMATELY 1,000 WATTS TO DEMONSTRATE EFFICIENCY, STABILITY, LOAD SHARING, AND LOW ELECTROMAGNETIC EMISSIONS.
