Motor Control, Part 5: Space Vector Modulation

Space vector modulation (SVM), also known as space vector pulse width modulation (SVPWM), is a common technique in field-oriented control for induction and permanent magnet synchronous motors (PMSM). SVM generates the pulse width modulated (PWM) signals to control the switches of a three-phase inverter, which then generates the three-phase voltages required to drive the motor at a desired speed or torque. Learn how SVM generates a voltage vector at any given angle and magnitude by alternating between basic and null vectors. This video also compares space vector modulation to sinusoidal PWM, which is another commonly used method for motor control. SVM lets you fully utilize the DC source voltage and increases bus utilization by 13.3% over sinusoidal PWM.
