This is only for self training I've been trying to narrow out
how many types of PWM schemes are used in VFD's knowing that newer driver usually use IGBT's rather than older circuits such as sSchmitt trigger or schottky so rather than get in all the different types of of PWM I would like to refine my knowledge on the types used in todays drives thus far I've been able to narrow the list out to Sine coded possibly the same as Bang Bang. Freeform
and square does anyone know of any good articles that describe the
commonly used schemes as pertaining to VFD applications?
