Abstract

This paper presents a simple control technique applied to three-phase rectifier units with high power factor and equilibrated currents in the input. The rectifier unit is composed of three single-phase modules without neutral connection and independent power factor pre-regulation stages. In order to obtain equal power processing in each phase, the output current of each single-phase module needs only to be equal, once the output voltage is common to all of them. The same current in each module is ensured by the current mode control technique. Theoretical analysis of the control technique, along with experimental results are provided in this paper.
