Analysis of Electrical Circuits with Variable Load Regime Parameters

A. Penin graduated from Radio Department Polytechnic Institute in 1974, Odessa, Ukraine. His engineering interest relates to power electronics. He worked (1980-2006) in the design office of solid-state electronics of the Academy of Sciences of Moldova. His speciality is the elaboration of power supply systems. From 2006 he has been working in the Institute of Electronic Engineering and Nanotechnologies of the Academy of Sciences of Moldova. He continues independent theoretical research in electric circuit theory with variable regimes. He is a senior research assistant, PhD (2011). The author has more than 60 publications, 40 patents of Moldova, one European patent, and one book.
