This study thoroughly compares multiple single bidirectional and multiport converters (MPCs), highlighting the significant role of MPCs in multi-input and multi-output (MIMO) systems. MPCs offer a more efficient and cost-effective solution than multiple single converters, especially in applications involving photovoltaic (PV), electric vehicles (EVs) with storage systems, and power grids. This research emphasizes the importance of multi-input converters (MICs) in integrating diverse voltage sources. It notes the rising popularity of multi-output DC-DC converters in portable electronics, owing to their reduced component count, lower costs, and compact design. This paper emphasizes comparisons based on diverse aspects and applications, shedding light on recent developments in basic bidirectional converters. Additionally, it delves into the advancements in MPC topologies, focusing on efficiency, reliability, and modularity improvements. These advancements are crucial for harnessing cost reduction, simplicity, and compactness. Furthermore, this paper introduces an innovative multiport DC-DC converter tailored for integrating and managing renewable sources. This new converter design enhances PV system and battery storage performance by reducing power conversion steps, using fewer components, and improving voltage-boosting capabilities. Its unique bidirectional buck-boost structure allows for versatile connections between sources and loads with varying voltage and power requirements. The performance of this novel converter is evaluated through MATLAB/Simulink simulations under different scenarios. Experimental studies further validate its effectiveness, marking a significant contribution to power conversion and management in integrating renewable sources such as DC microgrids.

In this paper, a couple inductor‐based dc‐dc boost converter with extensible capability is presented. In the proposed converter, attaching extensions to input section alleviates input current ripple. Furthermore, the current sharing performance between different phases operates beneficially by expanding optimized boost converters, especially when a partial inequality exists among different switches' duty cycles and leakage inductances. The voltage conversion ratio of the proposed converter is also additionally optimized by a series of VMR's output capacitors. Meanwhile, not only the voltage stress upon the main switches is decreased but also the all switches are managed to be turned on with zero current switching technique. The voltage spikes across MOSFETs are eliminated by using the recycling energy of leakage inductances on the clamp capacitor. The topology of the proposed converter, steady‐state analysis, and design procedure is presented to indicate the merits of the suggested converter. A prototype circuit with a three‐phase interleaved boost converter, two number of diode‐capacitor in each VMR, and output power 660 W and 40–800 V conversion ratio is experimented to corroborate the validity of the presented structure.

“…Therefore, the factor of current ripple must be taken into account for designing an appropriate high gain dc-dc converter for FCs [37]. In [38], a high step-up three-port converter using CI has been presented which performs high input current ripple. To minimize the input current ripple, [39] utilized the interleaving technique in its modular structure.…”

In this paper, an extendable high step‐up topology is presented for the low input voltage applications, that is, fuel cell (FC) source. The proposed converter eliminates the pulsating input current and reduces the high input current ripple. Thus, the lifetime of this non‐linear source and energy flow is significantly improved. The high output voltage is achieved by using voltage multiplier cells (VMC) and a coupled inductor (CI) with reduced elements. Moreover, an auxiliary circuit is applied due to restoring the energy of leakage inductance in the CI. Therefore, not only all power switching devices are turned on under zero voltage switching (ZVS) but also the input current ripple is remarkably reduced to zero. Furthermore, normalized semiconductors’ voltage stresses are diminished. The reverse recovery problem of diodes and their turn‐off power losses at high frequencies are alleviated owing to their zero current switching (ZCS) turn‐off. In this paper, the performance of the proposed structure is investigated and compared with the traditional converters considering their voltage gain and voltage stress. Eventually, a 500‐W prototype of the proposed converter is built and tested to validate mathematical analyses.
