Abstract :
This paper presents a voltage doubler boost rectifier based on three-state switching cells for uninterruptible power supply (UPS) applications. Its main features are: high power factor, reduced conduction losses, weight and volume, simple control strategy, and connection between input and output enabling the use of inverter and bypass. A theoretical analysis, simulation results and experimental results from a 3 kW lab model are presented.
