Guest Editorial Special Issue Commemorating 40 Years of WEMPEC, 1981–2021

In the 1970s, a small community of pioneering researchers around the world in industry and academia were laying the groundwork for the discipline of solid-state power electronics as we know it today. Near the end of that formative period, the Wisconsin Electric Machines and Power Electronics Consortium (WEMPEC) was founded in 1981 by Profs. Donald W. Novotny and Thomas A. Lipo at the University of Wisconsin–Madison. Prof. Robert D. Lorenz joined the embryonic WEMPEC program faculty in 1984, bringing his unique expertise and passion for motor drive controls.
