Digital Demodulation of a Space Vector Modulated Three-Phase Pulse-Width Signal
Abstract
Pulse-width modulation (PWM) is widely used in generating variable three-phase currents. Space vector PWM (SVPWM) is one of its common implementations, but digital demodulation methods for SVPWM signals have been largely unexplored. This article presents an algorithm to reconstruct the modulating space vector from SVPWM signals. The work includes theoretical description, simulation results, FPGA implementation, and a practical example. The latter case involves a thorough discussion of PWM signal conversion.
