About the Author: Colonel Wm. T. McLyman

Colonel Wm. T. McLyman Colonel McLyman

Colonel McLyman has fifty seven years of experience in the field of Magnetics, and holds fourteen United States Patents on Magnetics-related concepts. He retired after 30 years a Senior Member of the Avionics Equipment Section of the Jet Propulsion Laboratory (JPL)(NASA) affiliated with the California Institute of Technology in Pasadena, California.

Throughout his thirty years at JPL in power conversion and as the Magnetics Specialist, he has written over seventy JPL Technical Memorandums, New Technology Reports, and Tech-Briefs on the subject of Magnetics and circuit designs for power conversion, fifty of which have been published by NASA. He has worked on projects for NASA including the Pathfinder Mission to Mars, Voyager I and II, Topex/Poseidon, Cassini, Galileo, Magellan, Viking, International Solar Polar, Hubble Space Telescope, Seasat, SIR-C, Mars Global Surveyor, NSCAT and the Deep Space Network.

He designed the Galileo signal rotary transformers used by the Command Data System (CDS), when the slip rings produced excessive noise on the 1-Mbit data bus. The performance of the signal rotary transformer exceeded all expectations. The rotary transformer on the Galileo Spacecraft lasted the life of the spacecraft, which was from 1989 to 2003 without a glitch. He has designed the Quiet Converter with its low noise environment into programs such as WF/PC-II, Articulated Fold, Mirror Actuators, (Hubble Space Telescope), MISR (Earth Orbiting System), Raman, and Mars 05 ONC, CCD Camera.

He is the author of four popular textbooks: "Magnetic Core Selection for Transformers and Inductors, Second Edition". "Designing Magnetic Components for High-Frequency DC-DC Converters". "High Reliability Magnetic Devices: Design and Fabrication". "Transformer and Inductor Design Handbook, Forth Edition". Through his company, Kg Magnetics, Inc., he markets a design and analysis computer program for transformers and inductors.

This program operates on Windows 95, 98, 2000, NT, XP and Windows 7. He has been on the lecture circuit for over twenty years speaking and doing seminars in the United States, Canada, Mexico, and Europe on the design and fabrication of magnetic components. He is known as a recognized authority in Magnetic design. He is the President of his company called Kg Magnetics, Inc., which specializes in power magnetic design, which was formed and incorporated in 1985.
