Abstract :
This paper presents a novel boost topology based on three-state switching cells for uninterruptible power supplies (UPS) applications. The main features of this converter are: reduced conduction losses on the controlled switches, magnetic components operating with the double of switching frequency reducing weight and volume, reduced high-frequency current ripple, simple control strategy that can be implemented with well know integrated circuits and connection between input power supply and converter output enabling the use of UPS inverter and by-pass. A theoretical analysis and experimental results from a 3 kW lab model are presented.
