Voltage Regulation Formula
The following equation is used to calculate the Voltage Regulation.
VR = (V1 – V2) / V1
- Where Where VR is the voltage regulation
- V1 is the no-load voltage
- V2 is the full-load voltage
V1 and V2 can be substituted whether you are looking at the up or down-regulation. In general V1 should be greater than v2.
What is a Voltage Regulation?
Definition:
Voltage regulation measures a system’s ability to provide constant voltage over a wide range of loads. In actual physical systems, this is performed by a voltage regulator.
How to Calculate Voltage Regulation?
Example Problem:
The following example outlines the steps and information needed to calculate Voltage Regulation.
First, determine the no-load voltage. In this example, the no-load voltage is 100 volts.
Next, determine the full-load voltage. In this case, the full-load voltage is 50 volts.
Finally, calculate the voltage regulation using the formula above:
VR = (V1 – V2) / V1
VR = (100 – 50) / 100
VR = .50 = 50%
