Inductor Power Loss Formula
The following formula is used to calculate the Inductor Power Loss.
PiL = Pcore + Pdcr + Pacr
- Where PiL is the Inductor Power Loss (watts)
- Pcore is the core power loss (watts)
- Pdcr is the dc resistance power loss (watts)
- Pacr is the ac resistance power loss (watts)
How to Calculate Inductor Power Loss?
The following example problems outline how to calculate Inductor Power Loss.
Example Problem #1
- First, determine the core power loss (watts). In this example, the core power loss (watts) is determined to be 10 .
- Next, determine the dc resistance power loss (watts). For this problem, the dc resistance power loss (watts) is measured to be 98 .
- Next, determine the ac resistance power loss (watts). In this case, the ac resistance power loss (watts) is found to be 745.
- Finally, calculate the Inductor Power Loss using the formula above:
PiL = Pcore + Pdcr + Pacr
Inserting the values from above and solving yields:
PiL = 10 +98+745 = 853 (watts)
Example Problem #2
Using the same method as above, determine the variables required by the formula. For this example problem, these are:
core power loss (watts) = 47
dc resistance power loss (watts) = 4
ac resistance power loss (watts) = 3
Enter these given values into the calculator or above yields:
PiL = 47 + 4 + 3 = 54 (watts)
