Active Inductor Technology – Intelligent Magnetics

Replace bulky inductors with intelligent magnetics

Active inductors replicate the function of large passive coils while reducing size, weight and material usage – and enabling adaptive system performance.

  • Same electrical performance as passive inductors

  • Up to ~70% reduction in energy storage

  • Adaptive control for improved power quality

What is Active Magnetics?

Traditional inductors rely on large magnetic cores and copper windings to store energy and suppress ripple. This leads to bulky components that limit system power density.

Active magnetics replace this approach by combining:

  • a reduced physical inductor

  • power electronics

  • real-time control

Active magnetics replaces traditional passive inductors with a controlled system that emulates inductive behavior using power electronics and real-time control. This approach enables significant reductions in size, weight, and material usage, while maintaining equivalent electrical performance.

By actively canceling ripple and regulating current dynamics, active inductors enable higher power density and improved system efficiency in applications such as motor drives, grid-connected converters, and DC-link filtering.

Technical foundation

Beyond Passive – Intelligent Control

Unlike passive inductors, active magnetics introduce adaptive functionality.

The system continuously adjusts its behavior based on real-time conditions, allowing optimization of:

  • harmonic distortion (THD)

  • current ripple

  • system stability

Key impact

  • up to 50% reduction in THD

  • significant reduction in ripple

This transforms the inductor from a passive component into an intelligent system function.

This solution can be combined with Active Capacitor technology to further optimize DC-link performance.
