Thanks. Lee. I need to study your reply. I need to get to work.
You're welcome! This is a complicated subject. Remember, electric motors
and inverters have had 100+ years of development by some of the
brightest minds in science and engineering -- all the way from Edison,

I can conclude from what you say that during regen mode none of the
IGBTs are energized. Therefore, only during drive operation are the
IGBTs switched. Sin

regen when at very low RPMs?
OK, the first key to understanding is that the six IGBTs each have a
diode connected across it. The six diodes are wired in a standard
3-phase

Robert,
An AC motor is by definition a motor that needs 3-phase (or more) AC
power. The direction of power (acceleration or braking) is only
determined by the phase (direction) of the current.
So, an A

In order to accomplish regen with an AC inverter on an all electric
vehicle are the IGBTs modulated or is a buck boost circuit added to the
inverter?
