| Paul L. Schimel
 | Paul Schimel spent his early years developing a wide ranging interest in all this electrical and mechanical, investigating and eventually repairing all types of equipment. He was working conventional machine tools and welding by 14. Through high school, he fixed most anything that was breakable including yard equipment, two-way radio gear, power tools, TVs, and stereos. He attended the School of Electrical Engineering at the University of Illinois at Urbana Champaign, specializing in power electronics where he earned a BSEE degree.
After this, he spent eight years in successful design engineering roles in consumer equipment including power supply design for projection and direct view televisions and telecommunications equipment including ring generators, battery rectifiers/eliminators, dc-dc converters, and UPSs—both switch-mode and ferroresonant. He then moved on to field applications engineering where he has spent the last six years on power management support and design work for Unitrode/TI, Fairchild and International Rectifier. He has assisted successful designs from mW to MVA and from prototype stages to finished end equipment. He moonlights in broadcasting, antique test equipment restoration, metal working, wood working, TIG welding, loudspeaker building, and amateur radio (K5NJP). He holds a commercial radio telephone license, a refrigeration license, and PE license. Mr Schimel holds several patents on magnetic structures for power electronics and novel circuitry. | | Articles written by Paul L. Schimel in How2Power Today: |
