QUESTION 4 An induction motor is driven by a six-step converter as shown in Figure 4(b). The voltage at the DC link, Vdc is 200V. At normal full-load operation, the motor current is 25A. The stator resistance is 0.502. The FWM technique is used during dynamic braking. From the information given, express the duty ratio of the FWM (assume that the braking current is three times the rated value) Figure 4(b) 5
