1. What is an EE Core Inductor Design Calculator?

Definition: This calculator determines the inductance of an EE core inductor based on the core's AL value and number of winding turns.

Purpose: It helps electrical engineers and hobbyists design inductors for power electronics, transformers, and other electromagnetic applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Inductance (henrys)
• \( A_L \) — Inductance factor (henrys per turn squared)
• \( N \) — Number of turns

Explanation: The AL value is multiplied by the square of the number of turns to calculate the total inductance.

3. Importance of Inductor Design

Details: Proper inductor design is crucial for energy storage, filtering, and impedance matching in electronic circuits.

4. Using the Calculator

Tips: Enter the AL value (typically provided in the core datasheet) and the desired number of turns. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find the AL value?
A: The AL value is specified in the ferrite core's datasheet, usually in nH/turn² or μH/turn².

Q2: How does air gap affect the calculation?
A: Air gaps reduce the effective AL value. Use the gapped core's AL value if available.

Q3: What's a typical AL value range?
A: Common values range from 10 nH/turn² to 10 μH/turn² depending on core material and size.

Q4: Can I calculate turns needed for a specific inductance?
A: Yes, rearrange the formula: \( N = \sqrt{L/A_L} \)

Q5: Does this account for saturation?
A: No, this only calculates inductance. Check current ratings separately to avoid core saturation.
