SBIR-STTR Award

Energy to Power Solutions (e2P) has teamed with quench detection (QD) expert Dr. Yuri Lvovsky (retired GE), Dr. Sastry Pamidi of the Center for Advanced Power Systems (FSU-CAPS), and American Superconductor Corporation (AMSC) to design, fabricate, and test a robust, reliable, and low cost QD system. e2Ps proposed system is a vastly different quench avoidance system that will provide multiple levels of noise cancellation, thus providing it with a QD threshold sensitivity far beyond what is possible using uncompensated systems, acoustic emissions, or even optical techniques. e2Ps proprietary system is a quench AVOIDANCE system that is insensitive to mechanical vibrations (e.g. ocean/sea wave impact, periodic weapon discharge, nearby mine detonation, GM cryocooler, etc.) and extremely low cost, making it technically and economically suitable for rapid implementation on the Navys unmanned HTS MS platform.Quench Avoidance,Degaussing,quench,Quench Detection,HTS,High temperature superconducting,Mine Sweeping

Energy to Power Solutions (e2P) has teamed with the Florida State University’s Center for Advanced Power Systems (FSU-CAPS) to design, fabricate, and test a robust, reliable, and low-cost Quench Detection and Quench Protection (QDQP) system. Our proprietary Intelligent QDQP (or I-QDQP) system uses a proprietary technique to cancel the HTS coil’s inductance leaving only the desired HTS coils resistive signal. e2P’s I-QDQP system is immune to acoustic interference/vibration and wave oscillation, making it extremely robust and reliable for the Navy’s HTS MS mission platform. During the Phase I effort, test results on e2P’s I-QDQP system showed inductive Noise Rejection Ratio’s (NRR) greater than 10,000 and surprisingly was so sensitive that during AC evaluations at FSU-CAPS, the I-QDQP system could also measure the HTS coils’ AC loss at applied transport currents of Irms far less than the DC Ic value, thus adding an entirely new/unexpected feature to our system. The proposed I-QDQP system can be used on both previously wound HTS coils as retro-fit enhancements and new coil construction making this an extremely versatile system. The proposed Phase II effort will focus primarily on new coil construction using our technology, which is best suited for the far more difficult AC modality HTS MS operation.
