The proposed high thrust linear actuator has three innovative elements. The first is the use of a switched reluctance motor, which is the most rugged and fault tolerant of all motor types. The second is the use of power electronics with SiC power semiconductors, which are rugged, have much better… More

78497S Electronic power conversion systems (PCS) introduce major cost and reliability issues in most DER (Distributed Energy Resources) and energy storage systems. To address these problems, this project will develop a SiC-based converter, scalable to ratings of over 500 kW, that will provide… More

78772 Wave energy is a vast resource that should be included in the mix of energy resources serving the public. It offers the benefits of most renewable resources: no dependence on costly fuels of limited supply, no effluent, little impact on animal and plant habitat and, when located off shore,… More

Silicon carbide (SiC)semiconductors offer revolutionary improvements in power electronics due to much lower conduction and switching losses, higher switching frequencies, higher voltage capability, higher operating temperatures and other superior properties relative to standard silicon. Losses in a… More

The extraction of electrical energy from ocean waves will make a major contribution to the generation mix by a renewable source which has little impact on the environment. This requires a complex generating system, the key subsystem of which converts the linear motion of waves into electricity. The… More

The applicant will develop a bi-directional converter that links ac and dc buses, and provides galvanic isolation with a high frequency transformer. The proposal exploits the best topology and approach to modularization identified in previous work carried out for ONR at Arizona State University. … More

The applicant is proposing a method for scavenging heat generated by power semiconductors in solid state converters used by the Navy and others. Thermoelectric devices (TEDs) are inserted in the device package in such a way that the thermal path is not only not impaired, but is in fact enhanced by… More

Variable speed rotors will give helicopters several advantages: higher top speed, greater fuel efficiency, momentary emergency over-power, resonance detuning capability and a reduction in noise. The applicant proposes to develop such a system using a doubly-fed planetary gear box with advanced… More

The applicant will develop a compact bi-directional converter with galvanic isolation for linking the power buses of the zones of future Navy ships. The converter can be used to reconfigure the zones to minimize the number of zones taken out of service due to damage or other type of failure. High… More

This SBIR Phase I research project will lead to an electrical panel with modules that provide interfaces between the electrical grid and the residential customer?s on-site loads and other energy systems. Through the use of interactive solid state meters, the utility will be able to intelligently… More

Pluggable EVs will represent a substantial electrical load that must be served when most advantageous in terms of price and grid stress. However, PEVs can also become a resource themselves if the battery storage can be used to support the grid or the customer
