An unity power factor front-end rectifier for DC power systems

This work is focused on the design of the controller for a single phase rectifier, which represents the last generation interface between utility and DC power systems. Such kind of front-end converter allows mitigating harmonic power quality problems caused by traditional diode bridge rectifiers. This converter should absorb current with low harmonic and near unit power factor, moreover it should allow power reversal. In this paper, the design has been fully investigated with the help of theoretical analysis and experimental results are shown.
