Function
Connected to rotor winding. Modulates the
amount of power fed back into the power
system and controls motor speed.
Connected to power system.
Matches system voltages.
Uses the zero crossing transformer for
bumpless transfer to
control offers reactive power compensation by
changing the flux length for system power
factor correction, which eliminates the
requirement of capacitor bank.
