Question 1

three-phase, half-wave rectifier

Answer 1

can only be used in wye configuration

Question 2

three-phase, half-wave rectifier “form factor”

Answer 2

Eaverage = 1.17 x Ephase

Question 3

three-phase, full-wave rectifier “form factor”

Answer 3

Eaverge = 1.35 x Eline

Question 4

three-phase, half-wave rectifier “ripple frequency’

Answer 4

60 x 3 = 180 Hz

Question 5
