Synthetic Space Vector Modulation

Abstract

Alternating current motors are used throughout the fleet because of their rugged construction and nearly maintenance free operation. Since the U.S. Navy is exploring and acting on the possibilities of DC distribution systems, the need exists for simple, reliable three-phase voltage source inverter (VSI) powered induction machines. Until recently, VSIs utilized a pulse width modulation (PWM) scheme controlling the frequency and amplitude of each phase. A novel and simple hardware centered VSI controller was designed, simulated, built and tested featuring a type of space vector modulation (SVM). Design criteria evaluated such as VSI frequency response, switching losses, dead-time and SVM switching sequences were considered. Specifically, modulo-6 and 12 synthetic SVM units were evaluated for future Department of Defense use.
