Foc pwm

WebAug 19, 2024 · SVPWM and SPWM are two modulation techniques commonly used with power converters. The purpose of a modulation scheme is to translate a voltage reference into a sequence of switching signals, in order to produce that reference at the output of the converter. While both techniques share similar acronyms, they have fairly different … WebField Oriented Control (FOC) is a performant AC motor control strategy that decouples torque and flux by transforming the stationary phase currents to a rotating frame. Use FOC when rotor speed and position are known and your application requires: High torque and low current at startup. High efficiency. Equations
