Three-phase voltage doubler rectifier based on three-state switching cell for Uninterruptible Power Supply applications using FPGA

This paper presents a three-phase voltage doubler rectifier based on three-state switching cells for Uninterruptible Power Supply (UPS) applications using FPGA. Its main features are: high power factor, reduced conduction losses, weight and volume, simple control strategy based on One-cycle Control (OCC), and connection between input and output enabling the use of inverter and bypass. A theoretical analysis, simulation results and preliminaries experimental results from a 9 kW development stage lab model are presented.
