Question:

A 100-hp, three-phase, 60-Hz, four-pole, 1750-rpm, 0.85-pf induction motor operates with VFD connected to 460-V lines. The VFD design has CSI fed from a dc link. If the motor needs to run at 980 rpm, determine:

(1) The rectifier firing delay angle and

(2) The VFD output voltage at the motor terminals.
