Abstract

With the escalating adoption of electric vehicles worldwide, the demand for efficient charging solutions has become paramount. Power factor correction (PFC) technology, known for its high power factor and minimal input current harmonic distortion, has gained prominence in the quest for advanced charging systems. This project delves into the intricate design and optimisation of an interleaved PFC converter employing Sic Mosfet module with 3 integrated boost legs. The ability of the interleaving technique to maintain acceptable efficiency across a wide range of output powers via phase-shedding management is a major advantage. The design and optimisation of the boost inductor and EMI filter under such operating conditions to increase power density, however, has not been thoroughly investigated. As a result, the primary goal of this study is to investigate various aspects impacting the performance of a single phase three stage interleaved PFC converter to maximise its power density.
