Our Industrial Experience


United States Army Research Laboratory – 2800 Powder Mill Road, Adelphi, MD 20783

Dynapower - Army Research Laboratory

“Mr. Chirvasuta installed several large pieces of electrical equipment, specifically a three-quarter megawatt variable frequency power supply and a 400 HP dynamometer at the Power Center of the Army Research Laboratory. The quality of work Mr. Chirvasuta has done for us was excellent.” Thomas F. Podlesak, Ph. D., Leader for Power Conditioning Team U.S. Army Research Laboratory May 2003

18th Annual HEART Conference, Anaheim, California Development of a Practical Counter-Rotating Fly-wheel Debris Mitigation System     by Emanoil Chirvasuta and others

"The CRF system represents a significant improvement over prior embodiments of fly-wheel-based debris mitigation systems. Numerous engineering improvements have led to precise, reliable operation with greatly improved debris mitigation characteristics."    March 21-24, 2000

“Mr. Chirvasuta was employed as a contractor for the Naval Research Laboratory in Washington, DC during the period July to October 2002. During this period Mr. Chirvasuta demonstrated outstanding capabilities in electrical circuit design, construction, and operation of advanced electrical systems. His job was to design a rep-rated solid state switch based on stacked IGBTs. He started the project using a computer based circuit code and based on this design study he assembled a bread board circuit. After one month of testing and optimizing the switch the design was finalized and integrated into a high voltage pulser unit. During his several months of work here at the Naval Research Laboratory Mr. Chirvasuta utilized his experience in electric circuits along with his mechanical design skills to produce a unique piece of electrical hardware. The system is on the cutting edge of high voltage pulsers. His performance made it obvious that he had years of experience in designing and building complex electrical systems. Mr. Chirvasuta certainly has extensive expertise in electric circuit design and great familiarity with standard and advanced electrical diagnostics.”    Dr. Robert A. Meger Head of Charged Particle Physics Branch, Plasma Physics Division
