A 200-hp, three-phase, 60-Hz, six-pole, 1150-rpm, 0.90-pf induction motor operates with VFD connected to 480 V lines.

Question:

A 200-hp, three-phase, 60-Hz, six-pole, 1150-rpm, 0.90-pf induction motor operates with VFD connected to 480 V lines. The VFD design has a current source inverter (CSI) fed from a dc link. If the motor needs to run at 1/2 × rated speed, determine:

(1) The rectifier firing delay angle and

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