Intermediate Transient Support of High Rate and Pulsed Loads

With the Navy proceeding on its goal of an all-electric ship, innovative R & D methodology is needed to model and validate high rate, intermittent energy storage and control architectures that can rapidly accept high intermittent currents to load-level prime movers during the pulsed-power duty cycle. This proposal offers a solution to mitigate the intermittent disturbances to the ship"s distribution system resulting from applications requiring pulsed power. The solution offered is based upon Superconducting Magnetic Energy Storage (SMES). Our proposal team of the University of Wisconsin, Curtiss Wright Advanced Products and Systems Division (CW-APSD) and NDI Engineering offer extensive experience and skill set in the development of SMES specifically and in the area of cryogenic methods in general. The notional SMES design offers the required power and energy with a minimum weight, volume and cost when compared to capacitative energy storage methods. The charging, discharging and pulse power forming network proposed is a unique formulation of IGBT based switching for maximum control of power flow. The expected results of this program will be an HTS SMES based energy storage device such that with minimum weight and volume will efficiently provide the transient power required of pulse loads.
