Dennis M. Darcy

Dennis Darcy is a patent agent in the firm's Boulder office with a background in electrical engineering. He has experience developing cyber programs for electric utilities and power plants, and embedded control systems and components for a well-known laboratory in Cambridge, Massachusetts. Dennis also worked in the power and controls group at that same laboratory developing electronics for undersea vehicles, and space systems, as well as guidance navigation and control. Dennis was Chief Technology Officer for a large format energy storage development corporation, where he developed and established the company's grid scale energy storage as well as an extensive patent portfolio. He was also Director of Engineering for SatCon Technology Corporation in Cambridge, Massachusetts where he developed a wide range of power and control electronics, power drives, and magnetic bearings for automotive, industrial, commercial, and military customers. For a commercial medical imaging company, Dennis worked a MRI power systems group developing both RF and gradient amplifier systems.

Dennis' direct areas of experience of include DC/DC DC/AC AC/AC systems, power electronics, sensor interfaces, analog/digital and digital/analog conversions, parallel power architectures, power and control schemes, MRI power Systems, PSPICE/MATLAB, 1.6 MW hybrid racecar electric drivetrain controller, high efficiency converters, DARPA design reviews, MIL STD power systems, PEBB at ONR, commercial automotive power systems, and sensor-less design.
