“…The work reported in Hu et al 61 shows a modified DAB converter interfacing a PV array, which proposes six transistors instead of the four used in the traditional structure. In addition, the converter includes a multiport transformer, which is intended to raise the 1.5 kV delivered by the PV array up to the 10 kV required by a microgrid.…”

Summary The dual active bridge (DAB) converter has high efficiency and versatility; hence, such a converter has been used to design photovoltaic (PV) applications with both step‐up and step‐down voltage capabilities. However, PV systems require maximum power point tracking (MPPT) controllers to track the optimal operation conditions; moreover, PV voltage controllers are required to reject load perturbations that reduce the MPPT performance. This paper describes the operation of a DAB converter in PV systems and compares the performance of the DAB converter with a classical boost solution. In addition, this paper also presents a systematic analysis of the control techniques for DAB converters in PV applications, which provides useful information for selecting the most suitable approach for a particular application.

“…The first approach adopted in literature to control DAB converters are PI and PID controllers, such as the works reported in previous works 35‐37,61‐65 . Those solutions provide a complete description of the model and design process, but the solutions are not validated considering perturbations.…”

“…Those solutions give a comprehensive explanation of the system model and schematic design, but they are not verified in the presence of perturbations. Furthermore, in [89][90][91], PI and PID controllers must take into account the linearization of the plant model, affecting the controller robustness, and do not often ensure the performance of a system. Another criterion is met in [92], which design nonlinear control techniques.…”

A power conversion system needs high efficiency for modern-day applications. A DC–DC isolated bidirectional dual active bridge-based converter promises high efficiency and reliability. There are several converter topologies available in the market claiming to be the best of their type, so it is essential to choose from them based on the best possible result for operation in a variety of applications. As a result, this article examines the characteristics, functionality, and benefits of dual active bridge-based DC–DC converter topologies and the other members of the family, as well as their limits and future advances. A high-frequency transformer is also an important device that is popular due to high leakage inductance in dual active bridge (DAB) converters. Therefore, a detailed review is presented, and after critical analysis, minimized leakage inductance in the toroidal transformer is obtained using the ANSYS Maxwell platform. Furthermore, this work includes a comprehensive examination of the control approaches for DAB converters, which is important for selecting the most appropriate technique for a certain application. The outcome of ANSYS Maxwell is integrated with a DAB-based boost inverter in the MATLAB/Simulink environment, and the results are validated with the help of an experimental prototype.

“…IsBDC are usually used when the voltage difference between the DC bus and the battery is large [71]. The presence of high frequency transformers and variety of components in various IsBDC topologies [60,61,[72][73][74][75][76][77][78] cause large converter size with applications in static energy storage. NIBDC are simple in structure, lightweight and simple to regulate.…”

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.
