Dear members,
Yesterday i look into the stuff of the series and shunt regulators.
I build the two circuits and did a few measurements.
These circuits are used for a better line and load regulation.
Line regulation = when there are variations on the power supply.
Load regulation = when there are variations on the current trough the load.
Please, Correct me if i'am wrong.
Sunt regulator:
Rs= 320
diode 8.2V
Rload1 = 460
Rload2 = 1.47k
When i measured the voltage over Rload(460), i measure 6.8V.
I measured that the current through Rs and Rload1 was the same.
When i measured the voltage over Rload(1,47k), i measure 8.2V.
I measured that the current through Rs was 10mA and through Rload2 was 5.5mA.
With this measurement i want to simulate the load regulation.(diffrent current).
Is that normal ?
Can i assume that i have the same problem as described in the link.
