WebSVPWM is the best computational PWM technique for a three phase voltage source inverter because of it provides less THD & better PF. SVPWM works on the principle that when upper transistor is switched ON; corresponding lower transistor is switched OFF. The ON and OFF state of the upper switches (S. 1, S. 3, S. 5) evaluates the output voltages. WebIn [20], a technique of vector space control of three-level voltage source inverter fed five-phase machines was presented. Using the same idea described in [20], in this paper a SVPWM voltage source is developed which is capable of supplying the two motor drive system with different rotor speeds.
