This book is part of a three-book series for the sequence of electric power electives taught in most large universities’ Electrical Engineering departments. Advances in hybrid-electric cars and alternative energy systems, coupled with the severe environmental problems associated with hydrocarbon-based fuels, are driving renewed interest in the electric energy systems (EES) curriculum at the Undergraduate level.
Ned Mohan has been a leader in EES education and research for decades, as author of the best-selling text/reference Power Electronics with Wiley and a series of textbooks self-published under the MNPERE imprint. Mohan leads a consortium of 80+ universities working to revitalize electric power engineering education. These texts are based on the integrated curriculum developed over nearly 15 years of research in education in this field.
