Research Breakthrough: 3D-Printed Toroidal Inductors Enable Next-Gen Power Densities

CAMBRIDGE, Mass. – Researchers at **MIT's Power Electronics Research Group have demonstrated the first fully 3D-printed toroidal inductor using a composite material containing suspended magnetic particles. This additive manufacturing technique allows for previously impossible geometries, integrating cooling channels within the core itself. The result is a component that can handle 40% more current in the same volume, paving the way for ultra-compact, high-power aerospace and military power modules.

                      Basic knowledge of Inductor Choke Coils Inductance coils are made of wires wound around an insulating tube one by one. The wires are insulated from each other. The insulating tube can be hollow, or it can contain iron cores or magnetic powder cores, referred to as inductors. Expressed by L, the units are Henry (H), Milli Henry (mH), Micro Henry (uH), 1H=10^3mH=10^6uH. A. Classification of inductance Classified according to the form of inductance: fixed inductance, variable inductance. According to the nature of the magnetic conductor: air core coil, ferrite coil, iron core coil, copper core coil. Classified by work nature: antenna coil, oscillating coil, choke coil, trap coil, deflection coil. Classified by winding structure: single-layer coil, multi-layer coil, honeycomb coil. B. the main characteristic parameters of the inductance coil 1. Inductance L The inductance L represents the inherent characteristics o...

  A Breakthrough in EMI Resistance: Common Mode Inductors Common mode inductors are gaining popularity for their effective noise-suppression abilities, particularly in high-frequency applications. By employing a bifilar-wound ferrite core, these inductors offer superior common mode and differential mode noise suppression. The high impedance created by the common mode current flowing through the coil ensures strong damping, which helps attenuate EMI signals and provides better protection for sensitive electronic devices. These small, high-quality inductors are essential for reducing interference in a variety of modern devices, from computers to LCD panels.
