Electrical engineering

Motors, inverter modulation, power stages, and digital controllers. Start with the modulation index, then see why SVPWM produces more output voltage than SPWM from the same DC bus.

PWM and space-vector modulation 2 parts

From the definition of the modulation index to the voltage gain of space-vector PWM.

1. The modulation index of pulse width modulation (PWM)
2. Why SVPWM Gives About 15% More Voltage Than SPWM, and Why the Number Changes With Your Definition
