Enter the power output, the power input, and the DC power into the calculator to determine the Power Added Efficiency.

The following formula is used to calculate the Power Added Efficiency.

PAE = (Po-Pin) / Pdc *100

• Where PAE is the Power Added Efficiency (%)
• Po is the power output
• Pin is the power input
• Pdc is the DC power

## How to Calculate Power Added Efficiency?

The following example problems outline how to calculate the Power Added Efficiency.

Example Problem #1

1. First, determine the power output. In this example, the power output is given as 40 .
2. Next, determine the power input. For this problem, the power input is given as  30 .
3. Next, determine the DC power. In this case, the DC power is found to be 20.
4. Finally, calculate the Power Added Efficiency using the formula above:

PAE = (Po-Pin) / Pdc *100

Inserting the values from above and solving yields:

PAE = (40-30) / 20 *100 = 50 (%)

Example Problem #2

Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:

power output = 50

power input = 15

DC power = 100

Enter these given values yields:

PAE = (50-15) /100 *100 =35 (%)
