Development of a Low-Cost, Low-Voltage Three-Phase Power Synthesizer for Use in Motor andSystems ExperimentsThe electrical engineering program at the University of XXX has revised its curricular treatmentof electrical power and electrical machines at several levels and for students in all engineeringmajors. Included in that change was a decision to limit students’ first exposure to three-phasesystems to voltage levels less than 25V and power levels less than 5W. Cost, safety, and thedesire to have a meaningful three-phase laboratory experience for students who have minimalknowledge of the subject were the major factors in making that decision. Another driving factorwas the availability of low-voltage three-phase motors commercially available at very low-cost(under $10), but disguised as three-phase generators in a variety of “green” consumer products.Several years ago, three initial synthesizers were prototyped using discrete digital componentsand tested, with positive results, on sophomore students in diverse engineering majors.Unfortunately, none of the prototypes were, at that time, developed into practical, stand-alonedevices.The project was reinitialized this year with the purpose of developing a practical, stand-alonethree-phase power synthesizer that could be dispersed throughout the educational community atlow cost. A team has designed such a unit and is assessing its usage in a sophomore circuitslaboratory setting as well as by junior-level electrical engineering students in an electrical powercourse. Assessment results, and a full design description of the unit are presented here.
