QorTek and Lockheed Martin Mission Systems and Sensors (LM MS2) are together proposing a new low noise integrated converter architecture that would significantly improve both low frequency noise rejection and the high frequency switching noise content and still fit within the confines of the design envelope. As the prime contractor for the MK48 CBASS torpedoMS2 is uniquely positioned to work with QorTek in both assuring that the developed units meet performance requirements and providing the technology transition path directly to the production line of the MK48. Low frequency noise that is not rejected by the power supply will couple to the sonar system hardware and will reduce the high performance extended bandwidth of the CBASS (Common Broadband Acoustic Sonar System) transmit and receive functions. The Phase II approach is to build this modular solution in line with Navy torpedo performance upgrade programs to counter the continuously evolving threat upgrades of the Mk-48. The central aim will be to fabricate and test this very low noise power supply solution that will enable full wide bandwidth utilization of the MK48 torpedo through its novel noise reducing injection signal circuitry, such that every stage within the power supply addresses noise reduction, rejection, emissions.
