“…Further, the OR solution does not provide a proper control of the operating point leading to waste of environmental energy. The modular solution features full control on the operating point of each individual input source but lower power conversion efficiency and higher complexity [24][25][26]. Multiple modules, each including a source and the corresponding power management system, are usually connected to a common power bus.…”

In this paper, a novel multi-input, single inductor architecture is proposed. An innovative hysteretic control strategy of both the output voltage and the sources operating point control is designed and tested. Benefits brought by the proposed architecture over existing solutions are widely investigated. As an example, the design of a 48 V dual input system which is fed by photo voltaic and thermo-electric generators is proposed. Design guidelines are given and simulation results are presented to test the efficiency of the proposed architecture.

“…Yet, multi-sourcing is not effectively achieved since a source matching is not provided. Alternatively, each renewable energy source is connected to a power converter stage and several modules are connected to a common DC bus [4][5][6][7]. A front-end power converter is connected to the common DC bus for a proper supply of the power load equipment.…”

In this paper a multisource renewable energy system simultaneously fed by photovoltaic and thermo-electric generators is proposed. The designed system provides a multiinput power converter which is properly controlled to achieve both output and input control. The output DC bus is regulated to achieve a proper supply of the output energy buffer. On each input port of the power converter a control on the source operating point is applied to achieve he maximum power transfer from each renewable source. Experimental results are shown to test the efficiency of the proposed solution.

“…System B is the only one that is not sensitive to this, because each energy harvester/storage device has an interface circuit that brings its characteristics into line with those required by the power unit. The most commonlyused harvester types are photovoltaic (PV) cells, wind turbines, and vibration energy harvesters [6], [5], [8]. This section reviews the capabilities of the existing technologies.…”

“…Illustrative examples of two multi-source energy harvesting systems, developed by the authors of this paper, are shown in figures 1 (the 'Smart Power Unit' [6], hereafter referred to as 'System A') and 2 (the 'Plug-and-Play Architecture' [5], 'System B'). In these examples, energy harvesters and storage devices are connected via a power unit to an embedded device (wireless sensor).…”

“…To increase the availability of energy, and address the drawbacks of existing single-harvester systems, a number of reported works have proposed the simultaneous use of several energy harvesters [3]- [6]. By using a small wind turbine [7] and a solar cell, for example, more energy can potentially be generated (and for a longer period per day) than if a single harvester is used.…”

Abstract-Energy harvesting allows low-power embedded devices to be powered from naturally-ocurring or unwanted environmental energy (e.g. light, vibration, or temperature difference). While a number of systems incorporating energy harvesters are now available commercially, they are specific to certain types of energy source. Energy availability can be a temporal as well as spatial effect. To address this issue, 'hybrid' energy harvesting systems combine multiple harvesters on the same platform, but the design of these systems is not straightforward. This paper surveys their design, including trade-offs affecting their efficiency, applicability, and ease of deployment. This survey, and the taxonomy of multi-source energy harvesting systems that it presents, will be of benefit to designers of future systems. Furthermore, we identify and comment upon the current and future research directions in this field.
