Email this article A new Adaptation in Bridgeless Interleaved Power Factor Correction design for High Efficiency
Abstract
Seeking the requirements of world’s energy conversions, developments are tracked. The research and development of the AC-DC conversion circuit for variable frequency control, which is closely related to human life. It uses the bridgeless rectifier circuit, coupled with the Interleaved Boost and “PFC” (Power Factor Correction) technology to design a high-efficiency AC/DC conversion circuit, to provide a load of 400V, 2KW. The system efficiency can reach up to 96%. The power factor is close to 1, the input current ripple is below 0.8A and the output voltage ripple is below 6V. This paper presents the comparison of various current control techniques employed for a bridgeless interleaved boost converter for improving the power quality. The major control strategies discussed in this paper are: peak current, average current mode and borderline current control.
