“…High Gain in BDC may also be achieved using coupled inductor by adjusting its turns ratio. Several authors proposed BDC using coupled inductors [45][46][47][48][49]. A converter in [45] is proposed to reduce the size of passive components while employing internal circuit parameters for achieving soft switching.…”

“…This converter provides a wide VCR both in the charging and discharging mode with a smaller number of components. Discharging and charging modes yield maximum efficiency of 95% and 96% respectively [49]. This converter suffers from high current stress at the LV side and high voltage spikes on switches caused by leakage inductances which in turn decreases the converter performance.…”

Bi-directional DC-DC converters are required for power flow regulation between storage devices and DC buses in renewable energy based distributed generation systems. The fundamental requirements of the BDC are simple structure, reduced switching components, a wide range of voltage gain, low voltage stress, high efficiency, and reduced size. There are different BDC topologies for different applications based on their requirements. Isolated BDC converters are large due to high-frequency transformers and hence used for static energy storage applications whereas non-isolated BDC is lightweight and suitable for dynamic applications like electric vehicles. This paper reviews and compares different non-isolated BDC topologies by carrying out theoretical analysis and validating them through simulation results. A comparative analysis is done to identify the most efficient topology for the distributed generation systems. Five 200W converters are simulated in MATLAB Simulink to validate their steady state performance.

“…For EVs powered by hybrid energy sources, the coupled inductor bidirectional converter (CIBC), as opposed to the SCBC, has higher performance efficiency due to its low-voltage stress and high-voltage gain (Farakhor et al, 2018;Zhang et al, 2018aZhang et al, , 2018b. In Ayachit et al (2019), a reduced-component CIBC for EV charging applications was suggested. This design is capable of a broad range of voltage conversion because it can operate both in boost and buck modes.…”

Electric vehicle technology has recently drawn a lot of interest on a global scale due to improved performance in its efficiency and the capability to solve the problems of carbon emission. As such, electric vehicles are the key to achieving sustainable development goals. This review article analyzes deeply the previous technical developments of electric vehicles, focusing on important topics like battery management systems, technologies of power electronics, techniques of charging, and the relevant algorithms and improvements. In addition, several critical problems, and difficulties are presented in order to pinpoint the gaps in the literature. To address the analysis of battery behavior, battery condition monitoring, real-time control design, temperature control, fault diagnostics, and efficiency of battery model are considered. This study highlighted the estimation techniques that predict the internal battery conditions such as internal temperature, state of health, and state of charge, which are difficult to be directly monitored and determined. A lithium-ion battery, a super-capacitor, and related bidirectional DC/DC converters constitutes the infrastructure of a hybrid power system. This review offers useful and practical recommendations for the future development of electric vehicle technology which in turn help electric vehicle engineers to be acquainted with effective techniques of battery storage, battery charging strategies, converters, controllers, and optimization methods to satisfy the requirements of sustainable development goals. Accordingly, this review article will be a platform and future guide for those who are interesting in the field of energy management and its development.

This paper presents a theoretical analysis and the experimental results of the bidirectional coupled inductor dc-dc converter for dc-bus voltage regulation and power compensation in dc-microgrid applications. In dc-microgrids, a power distribution system requires a bidirectional converter to control the power flow between dc-bus and batteries. Furthermore, the dc-bus needs to be kept stabilized within certain limits and the converter handles a large range of voltage variation in the accumulators. The proposed topology is also relatively feasible for low-input-voltage applications for interfacing energy storage elements, such as batteries, ultracapacitors with the high voltage dc-bus in electric vehicles.The converter allows greater voltage gain compared to classic non-isolated topologies and can better deal with the wide range of voltage variation imposed by the source/load. The operation principles, the DC voltage gain, the design of the filters, the voltage/current stresses and a comparison are discussed. The experimental results confirmed and validated the theoretical study as well as the converter performance so that the measurements performed obtained from a 600 W laboratory prototype.
