Abstract

An integrated magnetic for a low harmonics three-phase bidirectional front-end and also for AC/DC and DC/AC power converters. Its use enables reduction of the harmonics of the currents absorbed or injected to three-phase power line by using only one device which integrates a splitter and an inductor function. Compared to known solutions, cost, material and dimensions of the integrated magnetic device are reduced thanks to the magnetic core comprising three closed sub-assemblies and one or more jokes, separated by air-gaps from the sub-assemblies.
