The chargers for electric vehicles (EVs) are one of the main components for the development of EVs. This work discusses a single-port DC fast charger, which is useful for charging medium-powered EV batteries, especially two- or three-wheeler EVs. This charger works in two stages. The first stage of this charger consists of a switched mode rectifier (SMR), i.e., a rectifier followed by a boost converter. The double PI controller controls the boost converter for power factor correction (PFC) operation. An unidirectional phase shift full bridge (PSFB) isolated converter is employed in the second stage. With the help of the phase-shifted PWM control technique, PSFB's switches are controlled and charge the battery in constant current constant voltage (CCCV) mode. The problems like high switching loss, low efficiency, high noise, and use of extra snubber circuits are minimized with the help of a phase shift full bridge converter. The output has a single DC port that charges EV batteries, which are rated at 72 V and have a charging current of 25 A maximum, based on Bharat DC 001 standards. The effect of supply and battery voltage variations on the power factor, THD, and efficiency has been analyzed. The proposed EV charger has been simulated, and the results have been verified with the help of MATLAB/SIMULINK.
