Prof. Vančo Litovski was born in 1947 in Rakita, South Macedonia, Greece. He graduated from the Faculty of Electronic Engineering in Niš in 1970 and obtained his M.Sc. in 1974 and his Ph.D. in 1977. He was appointed as a teaching assistant at the Faculty of Electronic Engineering in 1970 and became a full professor at the same faculty in 1987. He was elected as a visiting professor (honoris causa) at the University of Southampton in 1999. From 1987 until 1990, he was a consultant to the CEO of Ei and was the head of the Chair of Electronics at the Faculty of Electronic Engineering in Niš for 12 years. From 2015 to 2017, he was a researcher at the University of Bath.. He received several awards including from the Faculty of Electronic Engineering (Charter in 1980, Charter in 1985, and a Special Recognition in 1995) and the University of Niš (Plaque 1985).

This book discusses larger signal amplifiers (denoted as PA). Large signal amplifiers are dealing with signals whose magnitude is such that the operation of the active element can no longer be considered linear. They are usually designed to get as much power gain and efficiency as possible. That is why they are often called power amplifiers. In this book, two implementations of PA are considered. First, it is of interest to obtain large signals (current or voltage) at the output of a cascade of direct coupled amplifiers. In this case, linearity, frequency response, and speed are the most important requirements. Second are real power amplifiers where the power delivered to the load is of primary interest. Of course, efficiency, linearity, and high frequency response are of interest, too. A very special attention is paid to modern power electronic components such as Power BJT, VDMOS, IGBT, SiC MOS, and GaN HEMT. DC and switching properties of all these devices are studied in much detail. This book also includes a set of appendices which cover: solved problems, SPICE simulation results for selected set of circuits, and a short review of microelectronic technology process

This book entails every reader to repeat (and verify) every single study provided by author by delivering all necessary data for the circuit to be simulated by the user on a platform which is free. This is a student-oriented textbook covering the subject of producing a DC power supply voltage (current and power) for electronic circuits and systems. The motivation for this book comes from the fact that practically all contemporary books on the power supply are power oriented. The community is obsessed by the renewables and energy delivering systems so that powering electronics is almost forgotten. The book presents facts that the design requirements for a converter differ if one looks for power supply for electronics, from the ones intended to be used in power delivering systems to large consumers. So, in this book, "all" existing solutions are re-considered from the point of view of applicability to electronics. Along the development of proper design procedures (and formulas) exhaustive analysis is performed looking to them from as many as possible aspects. It brings the reader much closer to the circuit than the "hand drawn" time domain responses distributed in the existing textbooks. A set of solved problems is added to further increase the acceptance of the knowledge delivered.
