Inductor Loss Equation:
From: | To: |
Inductor loss consists of two main components: core loss (hysteresis and eddy current losses in the magnetic core) and copper loss (I²R losses in the winding). The total loss affects the efficiency and temperature rise of the inductor.
The calculator uses the simple equation:
Where:
Explanation: The total power loss in an inductor is the sum of its core losses and copper losses.
Details: Accurate loss calculation is crucial for thermal management, efficiency optimization, and reliability prediction in power electronics designs.
Tips: Enter core loss and copper loss values in watts. Both values must be non-negative. For precise results, use measured or manufacturer-provided loss data.
Q1: What affects core loss?
A: Core loss depends on frequency, flux density, core material, and temperature.
Q2: How can I reduce copper loss?
A: Use thicker wire, lower resistance materials, or optimize winding geometry.
Q3: When is this calculation most important?
A: Critical in high-frequency, high-current applications where losses impact efficiency and thermal performance.
Q4: Are there other types of inductor losses?
A: Yes, but core and copper losses typically dominate. Other losses include proximity effect and radiation losses.
Q5: How does temperature affect these losses?
A: Core loss may decrease while copper loss increases with temperature due to rising winding resistance.
