This article presents the charging status of electric vehicles by implementing two different charging topologies and demonstrates the comparison of power factor corrector (PFC) and Boost Cascaded by Buck-Boost (BoCBB) topologies. The former topology charger operates in boost mode, while the latter topology charger can operate in both modes (buck and boost) with a wide range of output voltage ranging from 30 V to 500 V. Moreover, using the harmonic modulation technique, former topology charger operation results in reduced total harmonic distortion, more efficiency, and high input power quality than the latter one. They are also evaluated on the basis of charging time, and by using PFC topology, the battery is charged to 5% in 10 min, while by using BoCBB the battery is charged to 3% in 10 min. The model’s performance is verified by using MATLAB-Simulink.
