Space vector modulation - Wikipedia
Space vector modulation (SVM) is an algorithm for the control of pulse-width modulation (PWM), invented by Gerhard Pfaff, Alois Weschta, and Albert Wick in 1982. [1] [2] It is used for the creation of alternating current (AC) waveforms; most commonly to drive 3 phase AC powered motors at varying speeds from DC using multiple class-D amplifiers ...

2021年8月9日 · What is the space vector modulation technique (SVM) and how does it work? To answer these questions, this article introduces first the notions of active and zero space vectors and their representation in the Clarke referential. It presents then how to use space vectors to synthesize any output voltage with two or three-level inverters.
With the development of microprocessors, space-vector mod-ulation has become one of the most important PWM methods for three-phase converters [8]–[15]. It uses the space-vector con-cept to compute the duty cycle of the switches. It is simply the …
Space vector is a mathematical concept which is useful for visualizing the effect of three phase variables in space. Space vectors. Resultant space vector for load phase voltage or current are defined as, The space vectors VR(t) or IR(t) have both magnitude and angle.
