WebApr 10, 2024 · 0. I have modeled a SVPWM for a two-level, three-phase inverter. The modulation index for svpwm is selected as MI = 3Vref/2Vdc, the dwell time is selected based on sector and alpha (angle in each sector), the Vref is selected as 300, and Vdc is given as 500 volts, so based on the above formula, the MI index is 0.9. so the maximum value for … WebMoreover, I have recently done a research project on Dual inverter topology based on e-drive (with FOC) where I had to simulate ... -Development of 48V mild hybrid drive for 3 phase and 6 phase PMSM (with 0° and ... - Initialize dynamic interleaving for both 3 phase and 6 phase PMSM drive. - 12&24- sector based SVPWM designing ...
WebApr 28, 2024 · Answers (1) Looks like the problem is in the Universal Bridge. The dimension of 'g' input is expected to be 6 as we have 6 switching devices in a three-phase inverter. However, in the attached image the input 'g' is connected to a Pulse Generator that outputs only a pulse. Probably it is better to use a PWM Generator that would output 6 pulses.
