Generating Dc Flashcards
The DC generator converts AC to DC by swapping the connections between the wire coil and the generator outputs whenever the voltage in the could becomes negative.It does this using a blank.
Commutator.
How does a AC alternator work?
Uses diodes to cut off flow whenever it reverses direction.
DC generators and alternators produce a higher blank the faster they rotate.
Emf
DC alternators and generators alter with blank.
Engine rpm.
Why is a voltage regulator needed in a DC alternator and generator?
Voltage varies with engine rpm.
Hiw does a voltage control unit work?
Alters current flow.
What causes current flow reversal in an alternator/generator?
If the voltage of the alternator/generator goes below the voltage of the busbar
What happens if an alternator or generator experiences current flow reversal?
It becomes an electric motor and is driven by the battery.
True or false: the busbar is permanently live/on.
True
What does reverse current protection between the alternator slash generator and the busbar ensure?
Battery cannot drive the alt/gen
