A large family of pulsed rotating generators (compensated pulsed alternators and similar devices) previously used as power supplies for military purposes, especially in anti-armor applications (railguns, coilguns), are finding a large spectrum of industrial uses. They combine very efficient kinetic energy storage with fast discharge capabilities, providing power supplies for numerous applications. This paper outlines the electromagnetic and the electrodynamics of such power supplies and the expedient and efficient methods of modeling, analysis and design in fast discharging electromechanical systems. The methods are applicable to any magnetic media (ironcore, aircore, and mixed systems).
