With the ever increasing demand for making electric vehicles (EVs) more powerful, higher capacity battery packs are going to be installed in the EV. Fast charging of these battery are crucial for bringing parity between the EV and conventional vehicles. At PEMSES, a single stage EV charger is being developed to achieve more efficiency by using lesser number of semiconductor switches compared to conventional chargers having multiple power conversion stage. Higher power density will also be achieved by minimizing the use of magnetic components and using Wide Bandgap (WBG) devices like SiC with high switching frequency. Bidirectional power flow feature is being considered to pump excess power from the vehicle back to the grid to cater to peak loading conditions.
