1. What is the IHLP Loss Equation?

The IHLP (Inductor High-Performance Low-Profile) loss equation calculates total power loss in inductors by summing core loss, DC loss, and AC loss components. This helps in evaluating efficiency and thermal performance of inductor designs.

2. How Does the Calculator Work?

The calculator uses the IHLP loss equation:

Where:

• \( P_{core} \) — Core loss in watts (W)
• \( P_{dc} \) — DC winding loss in watts (W)
• \( P_{ac} \) — AC winding loss in watts (W)

Explanation: The equation sums all major loss components in an inductor to determine total power dissipation, which is crucial for thermal management and efficiency calculations.

3. Importance of Power Loss Calculation

Details: Accurate power loss calculation is essential for designing efficient power supplies, predicting thermal performance, and ensuring reliable operation of electronic systems.

4. Using the Calculator

Tips: Enter core loss, DC loss, and AC loss values in watts. All values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is core loss in inductors?
A: Core loss is the energy dissipated in the magnetic core due to hysteresis and eddy currents when subjected to alternating magnetic fields.

Q2: How is DC loss different from AC loss?
A: DC loss is due to DC resistance of the winding, while AC loss includes skin effect and proximity effect losses at higher frequencies.

Q3: Why is total power loss important?
A: Total power loss determines the temperature rise in the inductor, affecting system reliability and requiring appropriate thermal management.

Q4: How can I reduce inductor losses?
A: Use lower loss core materials, optimize winding design, operate at lower frequencies, or use larger core sizes to reduce flux density.

Q5: Are there limitations to this simple model?
A: This model provides a basic summation but may not account for complex interactions between loss components at very high frequencies or non-linear operating conditions.
