Abstract
A harmonic cancelling interphase magnetic device () comprising a magnetic core of rectangular shape with three wound legs () and two non-wound legs (), wherein the cross-section of said non-wound legs () is thinner than the cross-section of said wound legs (). The magnetic device is designed for a front end multi-pulse rectifier or inverter. Its use enables reduction of the harmonics of the currents absorbed or injected to three-phase power line. Compare to known solutions, cost, material and dimensions of the magnetic device are significantly reduced.
