“…Also, their efficiency is lower than the proposed converter due to the hard switching conditions. Moreover, simultaneous power delivery from the inputs cannot be achieved for Banaei et al In Harchegani and Mahdavi, input currents are continuous but the voltage gain is relatively low. Deihimi et al employs two switches.…”

In this paper, a non-isolated dual-input DC-DC converter with zero-voltage transition (ZVT) is proposed for renewable energy systems. The proposed converter has high step-up conversion gain without using any transformer or coupled inductors. The proposed structure consists of two boost cells, one diode-capacitor multiplier cell, and one ZVT auxiliary circuit. The main switches turn on and off under zero voltage condition and the auxiliary switch turns on under zero current condition and turns off under zero current and zero voltage conditions. Soft switching conditions, high efficiency, continuous current of input sources, low-voltage stress on switches, and returning the energy of the auxiliary circuit to the boost cell connected to the lower-voltage input are the main advantages of the proposed converter. The steady-state analysis of the converter and operation intervals are discussed. A 160-W prototype of the proposed converter is designed and implemented. Experimental results confirm the theoretical analysis. The efficiency reaches 96.7% at the nominal load by providing soft-switching for all switches. The proposed topology can be extended for multi-input applications by expanding the number of diode-capacitor multiplier and input boost cells.

“…• Sources charge battery individually or simultaneously [29] 3 4 3 characteristics are often integrated with ESS for energy buffering and optimal energy management to meet the load power demanded [23,29,101]. Multi-port energy transfer is essential in the electric/ hybrid vehicles, and hence converters which integrates multiple sources and provide energy transfer among them are widely used [8, 35, 45-47, 49, 50, 66, 102].…”

“…With the advent increase in the advancements of multiple input converters (MICs), researchers have focused on developing MIC structures for various applications. For instance, state-of-the-art emphasising the topology has been presented in [12][13][14][15][16][17][18][19][20][21][22][23][24], whereas, state-of-the-art discussed in [25][26][27][28][29][30][31][32][33][34][35][36] emphasises on the MIC for hybrid energy systems applications. Further, MIC for PV applications has been reported in [11,[37][38][39][40][41][42][43][44][45] and MIC for hybrid vehicles has been discussed in [33,35,[45][46][47][48][49][50].…”

Power electronics converters for DC-DC conversion are extensively used in various applications. Further, with an increase in demand for integrating multiple sources with distinct I-V characteristics, a change over from single input DC-DC converters to multiple input converters (MICs) has been observed in the recent past. MICs are widely used for effective integration of energy sources in various applications ranging from milliwatt to megawatt power levels and millivolt to several kilovolts of voltage levels. The combination of sources with respective energy buffering units allow for a new configuration and topology, which are quite confusing and challenging to pick one for a specific application. MICs are categorised based on their characteristics, and each category has its pros and cons depending on the application. Further, this study categorises and comprehensively reviews the MICs based on their characteristics. In this regard, this study aims to provide a clear picture of MICs and the general rules and framework for the selection of MIC topology for a specific application. Also, the key features and limitations of a few recently proposed MICs, followed by the selection of MICs for different applications are discussed.

A non-isolated high-voltage gain dual-input DC/DC converter with a zero voltage turn-off (ZVT) auxiliary circuit has been presented. Two photovoltaic (PV) modules can be connected to the proposed converter with separate maximum power point tracking (MPPT). The cost of whole PV power generation system can be decreased significantly as a single converter is employed instead of two converters. All switches can achieve ZVT by an auxiliary circuit, and turn-off switching losses can be decreased and the efficiency of the converter can be improved. Working principle and performance characteristics of the proposed converter are analysed in detail, a dual-input maximum power point tracking control algorithm has been designed for the proposed converter. An 800 W experimental prototype has been built to verify the theoretical analysis.
