Low Noise Torpedo Power Supply Navy SBIR FY2013.1 Sol No.: Navy SBIR FY2013.1 Topic No.: N131-032 Topic Title: Low Noise Torpedo Power Supply Proposal No.: N131-032-0523 Firm: Progeny Systems Corporation 9500 Innovation Drive Manassas, Virginia 20110 Contact: Geoff Short Phone: (401) 846-0111 Web Site: www.progeny.net Abstract: The MK48 Heavyweight Torpedo broadband sonar system performance is limited by the current power supplies used to power to the electronics in the torpedo. The broadband sonar system cannot operate to its full potential due to noise and ripple from these power supplies. Progeny Systems will leverage our extensive experience gained from our development and manufacture of low-noise power supplies, such as the Progeny designed Power Regulator Module (PRM) used in the MK54 Lightweight Torpedo, to develop concepts and solution for the MK48 Low-noise power supply. During Phase I, Progeny Systems will demonstrate the feasibility of our concept and approach by establishing performance goals based on the Navy requirements that will be verified by testing and analytical modeling. The re-designed power supply will have an input voltage of 275 VDC and will perform a DC to DC conversion to generate low output voltages from 3.3 VDC to 28 VDC with an output noise less than 0.15mVrms/rtHz and will be capable of providing an output power of approximately 1275 watts. The power supply shall reside in a volume of 225 cubic inches and weigh less than 13 lbs. Benefits: These state of the art power supply concepts could be used in avionics, vetronics, medical imaging and professional/commercial audio applications. Return
