Abstract

A DC–DC converter in an EV charging station is to regulate the DC voltage from the rectifier to the required voltage for battery charging. This ensures that a constant, stable, and safe charging voltage is provided to the battery However, if the EV charging is done only with a DC–DC​ converter, it results in poor Power Quality (PQ), with high levels of harmonic distortion and a low power factor. This can lead to longer charging times, increased energy costs, decreased battery performance and life, and introduce serious PQ issues. To address these issues, the Ferdowsi Converter is proposed is a combination of two interleaved Buck-Boost converters with a common input inductor as a solution with simplified PT control strategy presented, operated in operating in discontinuous conduction mode (DCM) is presented, which can achieve nearly unity power factor (PF) over universal input voltage range studied. The converter performs with fewer components, providing a charger input current that is in phase with the mains voltage, reducing the THD to below 5% under steady state and during variations in line and load side.
