“…Multi-input converters have been introduced in [9][10][11][12][13][14][15][16][17][18][19][20][21]; however, they do not consider a battery as a part of the converter. Therefore, these structures are not appropriate for application in DC drives because as noted earlier, if the power generated by the PV exceeds the output power of the DC motor, it is not possible to extract maximum power from the PV.…”

“…In addition, [1][2][3][4][5][6][7] merge traditional converters, such as boost and buckboost, together to obtain a multi-input converter. On the other hand, [9][10][11][12][13][14][15][16][17][18][19][20] have utilized different boost techniques, including voltage multiplier (VM) and voltage lift switched inductor (VL-SL), to reach a high voltage gain in the multi-input converter. Moreover, [21] has employed the four-stage voltage multiplier to reach a high voltage gain; however, the lack of a battery and a general power management strategy make it unsuitable for DC.…”

Here, a new hybrid DC–DC converter is presented to enable controlling a DC motor. Since renewable energy sources, including PV, FC, and batteries, are projected to be used extensively in the future, using interface converters becomes essential. Firstly, these converters must have a suitable voltage gain because PV and FC have a low voltage at the output. Secondly, such converters must be controlled correctly because PV and FC do not provide a constant voltage, they have different characteristics, and they may work in any operating point instead of the maximum power point. Therefore, a suitable controller is essential for extracting maximum power values from these energy sources. In this paper, the decentralized control method, as a multivariable control technique, has been used to control a PV/FC/battery DC–DC converter.

“…An adequate topology with a proper control is required to fulfill all these features. Aimed at constructing an appropriate converter for such applications, different composite topologies derived from classic buck and boost converters have been proposed [27][28][29][30][31][32]. It is known that multi-phase converters can reduce current stress by sharing the total power in each of the devices; however, it is also known that current imbalances may occur in these kinds of topologies [29,33,34].…”

“…Studies are still being conducted to control and compensate for this issue [34][35][36]. Some previously proposed topologies have limited output power [37][38][39] or impose an input voltage restriction among the sources [40][41][42], and others increase the number of components severely for each added source [32,40].…”

The use of several different sources to feed a load jointly is convenient in many applications, in particular those where two or more renewable energy sources are employed. These applications include energy harvesting, hybrid vehicles, and off-grid systems. A multi-input converter able to admit sources of different characteristics and select the output power of each source is necessary in such applications. Several topologies of multi-input converters have been proposed to this aim; however, most of them are controlled by simple strategies based on a small signal model of multi-input converters. In this work, a low cost high gain step-up multi-input converter is analyzed. A nonlinear model is derived. Using this model, a detailed design procedure is proposed. A 500 W converter prototype was constructed to confirm that the model predicted the real behavior of the converter. Using the nonlinear model, indirect voltage control of basic converters was extended to the multi-input converter. The obtained controller had a fast performance, and it was robust under load and input voltage variations. With the obtained model, the proposed design procedure, and the controller, a converter that was initially proposed for photovoltaic applications was enabled to be used in a broader range of applications. The herein exposed ideas for modeling, the design procedure, and control could be also applied to other multi-input converters.
