Voltage Regulation Flashcards
What is a voltage regulator in series?
variable resistor in series that can change output as voltage changes
As the load current increases, what happens to the voltage drop?
a larger voltage drop appears across the resistance
How do you maintain voltage across RL?
the value of resistance can be reduced
is this series circuit manual or automatic operated?
Manually operated
What is a Shunt Regulator?
the variable resistor in parallel that automatically changes as the output voltage changes
What happens when the shunt regulator is combined with the resistance of the power supply itself or an additional resistor?
it becomes a voltage divider
When does the shunt regulator resistance increase?
when the output voltage decreases
What does a voltage divider do?
distributes available voltage for loads with different voltage requirements
