D6 three phase AC rectifier cct Flashcards
1
Q
three-phase, half-wave rectifier
A
can only be used in wye configuration
2
Q
three-phase, half-wave rectifier “form factor”
A
Eaverage = 1.17 x Ephase
3
Q
three-phase, full-wave rectifier “form factor”
A
Eaverge = 1.35 x Eline
4
Q
three-phase, half-wave rectifier “ripple frequency’
A
60 x 3 = 180 Hz
5
