Experimental implementation of a passive current-injection high power factor three-phase rectifier

Current-injection rectifiers have found great interest in the Power Electronics community. This is mainly due to their high efficiency related to the reduced number of hard-switching devices, and their reliability with respect to other commonly known rectifiers. This paper presents an experimental investigation of a totally passive three-phase current injection rectifier with an emphasis on the parameters selection, the steady-state performance under rated and varying load conditions, and the system efficiency over a wide power range.
