A Novel Magnetic Device for Current Injection Based Three-Phase Low-Harmonic Rectifiers that Integrates the Current Injection Device and the Inductor

A special magnetic device intended for application in three-phase rectifiers with low harmonics is proposed in this paper. The device integrates functions of a standard current injection device and an inductor applied in the current injection network. Analysis of the device operation is presented and the design guidelines are given. The results are experimentally verified on a device designed for application in a rectifier with the rated power of 2 kW.
