“…where r DS,ON is the on-state resistance of the MOSFET, r ON Dk is the on-state resistance of the diode, I in is the average value of the input current, and V th is the threshold voltage of the corresponding device (MOSFET or diode). Based on the turn-off energy loss characteristic (w o f f ,DK , x o f f ,DK and y o f f ,DK ) provided by the manufacturer for the 100FIT test voltage (V 100FIT ; it is the voltage across the device such that there are 100 failures within 10 9 h of operation [106]; FIT is Failures In Time), we can estimate the average value of the switching loss in the diode [105] using Equation (10).…”

The transportation industry is transitioning from conventional Internal Combustion Engine Vehicles (ICVs) to Electric Vehicles (EVs) due to the depletion of fossil fuels and the rise in non-traditional energy sources. EVs are emerging as the new leaders in the industry. Some essential requirements necessary for the widespread adoption of EVs include sufficient charging stations with numerous chargers, less to no wait time before charging, quick charging, and better range. To enable a quicker transition from ICVs to EVs, commercial organizations and governments would have to put in a mammoth effort, given the low number of installed chargers in developing nations such as India. One solution to lower the waiting time is to have multiple vehicles charging simultaneously, which might involve charging two- and four-wheelers simultaneously, even though their battery voltage ratings differ. This paper begins by providing the details of the power sources for EV charging, the charging levels and connector types, along with the specifications of some of the commercial chargers. The necessity of AC-DC converters in EV charging systems is addressed along with the power quality concerns due to the increased penetration of EVs. Next, a review of the existing research and technology of isolated DC-DC converters for simultaneous charging of EV batteries is provided. Further, several potential isolated DC-DC converter topologies for simultaneous charging are described with their design and loss estimation. A summary of the existing products and projects with simultaneous charging features is provided. Finally, insight is given into the future of simultaneous charging.

In the bipolar DC network, the unbalanced loads and distributed power generations will result in unbalanced voltage on the DC bus and load side. The unbalanced voltage will lead to power losses and influence the regular operation of the power system. Voltage balancer (VB) can be introduced to adjust the unbalanced voltage in the bipolar DC network. This paper studies the regulation of unbalanced voltage in a bipolar DC network with voltage source converter (VSC), photovoltaic (PV) power generation and energy storage system (ESS) with the participation of VB. In this paper, it is proposed that the coordinated control based on VB can realize the voltage regulation of all parts in the bipolar DC network. It is pointed out that the proposed control strategy can realize adaptive adjustment of voltage droop coefficient. The MATLAB/Simulink platform is built to verify the effectiveness of the proposed coordinated control method for DC bus and load voltage regulation.
