Research

Prof. Leszek Stanisław (S) Czarnecki, Ph.D., D.Sc., for his whole scientific life was involved in the experimental and theoretical research on electric energy flow in circuits with voltages and currents that are not sinusoidal but distorted by electronic and power electronics loads. Description of this flow, referred to as a Power Theory (PT), is   a very controversial subject, studied and debated by thousands of scientis-ts for the whole XX century. Several different, mutually conflicting PTs and many power quantities that misinterpret electrical phenomena were introduced. The development of Currents’ Physical Components (CPC)-based PT by Prof. Czarnecki concluded that controversy. It also created fundamentals for methods of reducing excessive currents in electrical circuits by compensation. Before that, he falsified all other existing PTs. For the development of PT of three-phase circuits Prof. Czarnecki   was elevated to the grade of IEEE Fellow, a grade which can be awarded to only one of a thousand IEEE members, at the recommendation of five Fellows in the same research area. He was the second Fellow in Poland after  Prof. Janusz Groszkowski, the President of the Polish Academy of Sciences. For his contribution to the Power Theory of electrical circuits, Prof. Czarnecki was nominated to the Ch. Steinmetz Award.
