Due to the high energy requirements of the vehicle and the restricted availability of stops and parking, dynamic charging is the most practical method to support highway travel. Quasi-dynamic charging charges the car when it is briefly halted, as at a traffic signal or a bus stop, expanding the driving range and enabling EVs to store less energy.
The Quasi dynamic charging system charges the vehicle when it is stopped for a short time, such as at traffic light, thus extending the driving range and allowing reduction in energy storage for EVs.
The DC–DC converters serve as battery chargers in the back end of EV charging systems. The front-end AC–DC topology accomplishes the rectification operation using PFC, while the back-end DC–DC converter adjusts the voltage level from the rectification operation to make it appropriate for EV battery charging.
The two architectures for the EV charging station, namely AC charging systems and DC charging systems, are shown in Fig. 7. In AC charging systems, the secondary side of an MV-LV distribution transformer acts as a common AC bus which is connected to the onboard EV charger [ 22, 38 ].
The charging stations consist of two DC/DC converters is proposed. First DC/DC converter for connection of the battery to the charging stations and second DC/DC converter connected to the first DC/DC converter for connection of an EV to the charging station. The company claims home charging stations for electric vehicles.
Back-end DC–DC converter topologies are classified as isolated or non-isolated based on the presence of galvanic isolation between the input signal and the output circuit. An overview and comparison of the various DC–DC converter topologies used in EV battery charging are provided in this section.
