Prof. Leszek Stanisław (S) Czarnecki, Ph.D., D.Sc., IEEE Life Fellow,  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 Power Theory (PT), is a very controversial subject, studied and debated by thousands of scientists 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 Phenomena (CPC) – based PT by Prof. Czarnecki, concluded that controversy. It also created fundamentals for methods of reducing excessive currents in electrical circuits of any complexity by compensators. Before the development of the CPC, Prof. Czarnecki falsified all other existing PTs. For the development of the PT of three-phase systems with nonsinusoidal voltage Prof. Czarnecki was elevated to the grade of IEEE Fellow, a grade that can be awarded to only one for a thousand of IEEE members, at the recommendation of five Fellows in the same research area. He was in Poland the second IEEE Fellow after Prof. Janusz Groszkowski, the President of the Polish Academy of Science. For his contribution to Power Theory development Prof. Czarnecki was nominated for the Steinmetz Award.
