Space Vector Pulse Width Modulation (SVPWM) is a technique used to control the voltage applied to three-phase AC motors in applications like industrial drives and electric vehicles. It optimizes voltage utilization and minimizes harmonics, making it more efficient than conventional PWM techniques. SVPWM is used in topologies like three-phase voltage source inverters, multilevel inverters, matrix converters, and back-to-back converters to achieve benefits like higher efficiency, improved output quality, precise control, and reduced electromagnetic interference. While SVPWM provides advantages, implementing its complex control algorithms presents challenges.
