SUBRNARINE ELECTRONIC SYSTERNS POWER SUPPLY

THIS PROPOSAL OFFERS TO PERFORM CONFIRMATORY SYSTEM STUDIES , DESIGN DEVELOPMENT , AND BRASSBOAR DEMONSTRATION OF AN ELECTRONICS 270 VDC POWER SOURCE CONCEPT TO MEET THE REQUIREMENTS OF TOPIC NO. 91-204. THE CONFIRMATORY SYSTEM STUDIES WILL BE FOLLOW-UP TO U.S. NAVY STUDY EFFORTS COMPLETED IN 1981 ON THE SAME SUBJECT. THE PROPOSED POWER SOURCE CONCEPT IS AN EXPANDED VERSION OF ONE DEFINED AND EVALUATED IN THE 1981 NAVY STUDY . THIS POWER SOURCE IS REPRESENTED AS A HIGH RELIABILITY AND EFFICIENCY ROTATING RNACHINE CONSISTING OF AN INTEGRALLY RECTIFIED ALTERNATOR DRIVEN BY TWO INDUCTION MOTORS SIMULTANEOUSLY AND INDEPENDENTLY POWERED FRORN TWO 60 HZ BUSSES . IF ONE 60 HZ POWER FEED IS LOST THE MACHINE WILL CON.TINUE TO BEDRIVEN FROM THE SECOND 60 HZ FEED WITHOUT SERVICE INTERRUPTION . THE ALTERNATOR EXCITATION WILL CONSIST OF PERMANENT MAGNETS (PM). THE MACHINE WILL HAVE A SINGLE MOVING COMPONENT CONSISTING OF THE INDUCTION MOTOR ROTORS AND PM ALTERNATOR FIELD , ALL OF WHICH WILL BE MOUNTED ON A SINGLE SHAFT . THERE WILL BE NO ELECTRONIC CONTROL CORNPONENTS . THE INTEGRALLY INSTALLED OUTPUT RECTIFIERS WILL BE CONSERVATIVELY RATED TO ENSURE LONG LIFE AND RESISTANCE TO VOLTAGE STRESS EXPOSURE . THIS SHOULD RESULT IN A HIGH RELIABILITY POWER SUPPLY REQUIRING MINIMUM MAINTENANCE .
