“…The battery charger must then be capable of ensuring the conversion of energy flow in both directions, becoming bidirectional and capable of both charging and discharging. As a result, EVs with bidirectional battery chargers [3] can be connected into the smart grid, dramatically transforming the energy market. As shown in Figure 1, the EV charger can be considered as the association of two conversion stages [4]: an AC-DC part followed by an isolated DC-DC converter.…”

Bidirectional DC–DC converters are frequently chosen for applications requiring high power density such as in bidirectional electric vehicle (EV) chargers. Vehicle to Everything (V2X) technology makes the EV battery an electrical energy source. In this article, the use of a DC–DC LLC converter used in a bidirectional EV charger is reviewed. Different modeling approaches of the DC–DC LLC converter, such as small and large signal modeling, are discussed. Common modulation strategies applied to the DC–DC LLC converter in V2X mode, such as Pulse Frequency Modulation (PFM), Pulse Width Modulation (PWM) and Phase-Shift Modulation (PSM), are presented. The new challenge is to present the main characteristics and limitations of each modulation strategy in order to cover the whole operating zone of the EV charger in V2X mode. Furthermore, different control strategies based on a small or large signal model combined with different modulation strategies are highlighted. Linear and nonlinear controllers applied to the DC–DC LLC converter are discussed. Robust controllers are mainly highlighted regarding their advantage in ensuring the control robustness with respect to unexpected disturbances. A comparative study among modulation strategies as well as different control algorithms is conducted in terms of control performance and converter efficiency in V2X mode.

“…The size of OBC is minimized by introducing the voltage source converter at front end in place of the rectifier cum boost converter. The back end has multiple options of DC/DC converter in which DAB is preferred for the OBC [3]. The control technique for OBC with DAB topology is focused in [4] for obtaining the smoother operation and various DC/DC converter is discussed on reduction of converter size.…”

This proposed system is about bidirectional power flow for charger of an E-Vehicles. The charger connected with PV source is designed, modelled, and implemented. In this topology, the output charging current is regulated by DC-DC converter. The bidirectional interleaved isolated SEPIC converter is proposed in this paper for charging the electric vehicle. The multi-step constant current charging method is used for charging operation. This reduces the number of power electronic components, which in turn minimizes the power loss. Simulation is carried out in MATLAB/Simulink, and the results are obtained, which shows that battery can be charged with this topology.
