TīmeklisRecently, several pulse width modulation (PWM) techniques were developed, studied and applied to ac motors control. Two techniques were given a great deal of interest mainly, space vector modulation (SVPWM) and discontinuous pulse width modulation (DPWM). A. Theory of SV-PWM technique The SVM technique was firstly developed … Space vector modulation (SVM) is an algorithm for the control of pulse-width modulation (PWM). 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. There are variations of SVM … Skatīt vairāk A three-phase inverter as shown to the right converts a DC supply, via a series of switches, to three output legs which could be connected to a three-phase motor. The switches must be controlled so that at no time are both … Skatīt vairāk • αβγ transform • Inverter (electrical) • pulse-width modulation Skatīt vairāk
