Abstract
The paper presents a single-phase PFC converter built in the bridge configuration with split boost inductor placed on the AC side. The proposed topology enables decreasing of switching losses and limits the possible short circuit current through the transistor leg when its control signals temporary overlap. Both features make a construction of high power converters possible. In spite of an increased number of controllable power switches and the use of split choke, the converter's operation relies on a commercially available PFC controller (L4981). Due to the shifted pulses for the upper and the lower switches in the bridge the input current ripple and consequently the output voltage ripple are reduced. Based on a described principle an experimental model with nominal output power 1 kW has been built. Its functionality has been verified by measurements and harmonic analysis.
