## Power Added Efficiency Formula

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**

- First, determine the power output. In this example, the power output is given as 40 .
- Next, determine the power input. For this problem, the power input is given as 30 .
- Next, determine the DC power. In this case, the DC power is found to be 20.
- 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** **(%)
