Optimised Design and Implementation of SVPWM Switching sequences for Five level VSI

Implementation of space vector modulation for two level three-phase inverter using dSPACE DS1104

“…Various pulse-width modulation (PWM) techniques have been developed for industrial applications. The most widely used PWM schemes for three-phase voltage source inverters are carrier based sinusoidal PWM [6][7][8][9][10][11][12][13][14] and space vector PWM (SVPWM) [15][16][17][18][19][20][21][22][23]. The output voltage per phase for a sinusoidal PWM based three phase converter is limited to 0.5Vdc (peak value) and the line-to-line RMS voltage is 0.612Vdc.…”

“…The principle of vector modeling (SVM) consists in reconstructing the voltage vector a from eight voltage vectors. Each of these vectors corresponds to a combination of the state of the switches of a three-phase voltage inverter, it does not rely on separate calculations modulations by each arm of the inverter [15][16][17][18][19][20]. This technique follows the following principles: a)…”
