The space vector modulation technique operates on the reference voltage vector to generate appropriate gate signals for the inverter every PWM period, with the objective of achieving a continuously rotating space vector. Illustration of field-oriented control architecture with space vector modulation. Block...
Space vector modulation (SVM), also known as space vector pulse width modulation (SVPWM), is a common technique in field-oriented control for permanent magnet synchronous motors (PMSM).
2 SPACE VECTOR MODULATION FOR THREE-LEG VOLTAGE SOURCE INVERTERS 2.1 THREE-LEG VOLTAGE SOURCE INVERTER The topology of a three-leg voltage source inverter is shown in Fig. 2.1. Because of the constraint that the input lines must never be shorted and the output current must always be continuous...

Space vector modulation for three-level inverters The space vector modulation technique for two-level inverters can be generalized to three levels [2]. A three-level converter has three possible switching states per leg, denoted P (positive output voltage), N (negative output), and 0 (zero out...
In this paper, the control of an ac-dc-ac converter with a front-end diode rectifier and reduced dc-link capacitor based on the space vector modulation strategy is investigated. The modulation index is time-varying and determined by the instantaneous value of the dc voltage measured by a volt...
This paper describes a new Space Vector modulation (SVM) strategy for asymmetrical cascaded multilevel converters. A seven-level asymmetrical multilevel cascaded converter is considered. The modulation is carried out in a new coordinate system and is divided into two steps. First, the nearest switchi...

This model simulates a simple technique to implement space vector modulation. This method does not require too much computation at run time thus feasible for implementation with simple processors. Space vector trajectory is also plotted and can be checked at different modulation indexes using...
