Series Inductance Calculator
This calculator determines the total inductance of inductors connected in series. It’s useful in circuit design, filter creation, and power electronics where inductive components are combined to achieve a specific total value.
Total Inductance of Series-Connected Coils
Series Inductance Addition Formula
Where:
- $$L_{ ext{total}}$$ = total inductance (H)
- $$L_1$$, $$L_2$$, $$\ldots$$, $$L_n$$ = individual inductances (H)
Inductances in series simply add up, assuming no mutual coupling.
Given: Calculation:
Series Inductance – Calculation Example
When inductors are connected in series, their total inductance increases as the magnetic fields reinforce each other. This is commonly used in power supply filtering, tuning circuits, and energy storage systems. If there is significant magnetic coupling, mutual inductance must also be considered. This calculator is best suited for uncoupled or distantly placed inductors in a series configuration.
