James R. Jaeschke
Owner & Manager
Electronic Systems Consultants, LLC
MSEE ’68, BSEE ’66

Two years ago in September, James R. Jaeschke received his sixteenth patent, the latest in a long list of electrical engineering accomplishments. As the owner and manager of the Pewaukee, Wisconsin, based Electronic Systems Consultants, Jaeschke is building on more than 35 years of experience in the power electronics field.

He earned both his bachelor’s and master’s degrees in electrical engineering from UW-Madison, worked at Bendix Research Labs before serving two years in the U.S. Army including one year in Vietnam. He joined the Louis Allis Corporation in 1970 where he learned the industrial control and power conversion trade by applying eddy current, DC, AC 6 step, and AC PWM drive systems. He moved to the Eaton Corporation in Milwaukee in 1975. For more than a quarter century, Jaeschke advanced in the company, serving as an electrical design group supervisor, the manager of corporate research and development in both the electrical and the power conversion groups and served five years as the U.S. delegate to an IEC working group establishing drive standards.

The Eaton Corporation was one of two original companies that assisted in forming the Wisconsin Electric Machine and Power Electronics Consortium (WEMPEC) becoming the first WEMPEC sponsor. Jaeschke helped the company become an outstanding supporter and contributor to the consortium. In March of 1999, Jaeschke retired from Eaton and formed his own consulting company to help customers develop power electronic systems for fuel cells, and power circuit designs and study power line harmonic issues.

His contributions to the industry are best illustrated in his collection of patents, which include motor drive circuitry, a general purpose AC switch and special fiber optic- and radiant energy-activated solid-state switches.

Jaeschke and his wife Judy have four children and two grandchildren. Their hobbies include ham radio and sailing on his sailboat Electra, which he and Judy race every Wednesday night and cruise on the Great Lakes in the summer. He is currently on the board of directors of South Shore Yacht Club and is the webmaster of the club’s site, SSYC.org, plus three other yachting sites.
