Power Supply Efficiency Formula
The following formula is used to calculate the Power Supply Efficiency.
Eps = OP / IP * 100
- Where Eps is the Power Supply Efficiency (%)
- OP is the supply input power (watts)
- IP is the unit output power (watts)
How to Calculate Power Supply Efficiency?
The following two example problems outline how to calculate the Power Supply Efficiency.
Example Problem #1:
- First, determine the supply input power (watts). In this example, the supply input power (watts) is given as 60.
- Next, determine the unit output power (watts). For this problem, the unit output power (watts) is given as 100.
- Finally, calculate the Power Supply Efficiency using the equation above:
Eps = OP / IP * 100
Inserting the values from above and solving the equation:
Eps = 60 / 100 * 100 = 60 (%)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
supply input power (watts) = 50
unit output power (watts) = 200
Entering these values yields:
Eps = 50 / 200 * 100 = 25 (%)
