“…Previous review papers on multi-port converters have mostly considered different topologies or have discussed suggested applications for multi-port converters, with none focusing on decoupling methodologies in MAB converters [2,[137][138][139][140][141][142][143][144]. Triple-active bridge converters were briefly mentioned in [145].…”

Multi-port DC-DC converters are a promising solution for a wide range of applications involving multiple DC sources, storage elements, and loads. Multi-active bridge (MAB) converters have attracted the interest of researchers over the past two decades due to their potential advantages such as high power density, high transfer ratio, and galvanic isolation, for example, compared to other solutions. However, the coupled power flow nature of MAB converters makes their control implementation difficult, and due to the multi-input, multi-output (MIMO) structure of their control systems, a decoupling control strategy must be designed. Various control and topology-level strategies are proposed to mitigate the coupling effect. This paper discusses the operating principles, applications, methods for analyzing power flow, advanced modulation techniques, and small signal modelling of the MAB converter. Having explained the origin of cross-coupling, the existing power flow decoupling methods are reviewed, categorized, and compared in terms of effectiveness and implementation complexity.

“…This type of circuit is mainly used to improve efficiency in applications where voltage control is realized accurately, avoiding unwanted effects that occur with pulse width modulation (PWM) controllers. PWM control generates an undesirable dynamic effect on its output, generally as a result of a noisy output signal, as well as current spikes, elements that are not favorable for either the power supply or the circuit load such as another circuit or an application [2][3][4][5][6][7][8]. In the particular case of the Buck-type converter, there are two elements that can store energy, a coil and a capacitor, which reduces the amplitude of the effects generated by the commutation of the switches of the circuit, on the output signal [2].…”

This work proposes the design of a commutation function to solve the output voltage trajectory tracking problem in the DC-DC Buck power electronic converter. Through a Lyapunov-type analysis, sufficient conditions are established, taking into account the discontinuous model, to ensure asymptotic convergence to the desired trajectories. Based on this analysis, a state-dependent switching function was designed to guarantee the closed-loop stability of the tracking error. To validate the control performance, circuit numerical simulations were carried out under abrupt disturbances in the source and load of the converter. The results demonstrate that the voltage tracking at the output of the converter is satisfactorily achieved.

“…This innovative system can comprise many different input RESs that will be combined through multiple input power converters that can handle various input suppliers and merge their benefits to give a regulated output for a number of uses. In the scientific literature, two architectures for DC-DC translation have been published: single-port architecture (SPA) and MS [9]. Numerous sources are integrated at a shared DC side in the conventional configuration, and each source is subjected to a separate DC-DC conversion stage, with each converter functioning separately [10].…”

The integration of clean energy sources (CESs) into modern power systems has been studied using various power converter topologies. The challenges of integrating various CESs are facilitated by the proper design of multi-port power converter (MPPC) architecture. In this study, a brand-new two-stage MPPC is suggested as a solution to the intermittent nature and slow response (SR) of CESs. The suggested system combines a DC\DC and a DC\AC converter and storage unit, and the suggested circuit additionally incorporates a number of CESs (PV\wind\fuel cell (FC)). This article discusses the power management and control technique for an integrated four-port MPPC that links three input ports (PV, wind, and FC), a bidirectional battery port, and an isolated output port. One of the recent optimization techniques (Harris Hawk’s algorithm) is applied to optimize the system’s controller gains. By intelligently combining CESs with complementary characteristics, the adverse effects of intermittency are significantly mitigated, leading to an overall enhancement in system resilience and efficiency. Furthermore, integrating CESs with storage units not only addresses SR challenges but also effectively combats intermittent energy supply. The proposed system exhibits improved dynamic capabilities, allowing it to efficiently distribute excess energy to the load or absorb surplus energy from external sources. This dual functionality not only optimizes system operation but also contributes to a reduction in system size and cost, concurrently enhancing reliability. A comprehensive investigation into operational principles and meticulous design considerations are provided, elucidating the intricate mechanics of the suggested MPPC system. Employing MATLAB/Simulink, the proposed architecture and its control mechanisms undergo rigorous evaluation, affirming the feasibility and efficacy of this innovative system.
