“…In this section, an overview of the recent architectures and techniques focusing in energy harvesting from multiple heterogeneous sources is provided [50][51][52][53][54][55]. Energy harvesting from multiple sources is a more robust method for powering Internet of Things (IoT) nodes and similar wireless systems compared to harvesting from a single source.…”

“…In Figure 23, the concept schematic of the MI DC adder combiner is shown. A dual-input dual-output DC-DC converter (DIDC) topology is introduced in [54]; the proposed system can operate in single-and dual-input modes, as well as in dualoutput mode using two energy sources. The system is developed using a single inductor, and fewer switches and other passive components, and it achieves low power losses and high level of reliability as an energy harvester.…”

The Internet of Things (IoT) has found application in many components of implantable medical devices, wearable smart devices, monitoring systems, etc. The IoT devices are conventionally battery powered, even though, in several low power applications, they can also be powered using energy harvesting technology. Independently of the power sources (if batteries or environment), efficient and robust power converters must be designed to provide the small and distributed energy required by such IoT devices. This review paper will first provide an overview about the power consumption in IoT devices; second, it will discuss the most recent research and advance in the field of fully-integrated or embedded DC/DC converters, starting from high-performance integrated charge pumps or embedded inductive boost converters for specific harvesting sources (temperature, solar, and so on), to novel DC/DC converters for multiple energy sources.

“…But the converters in Akar et al 2,3 handle the situation, because of including the mode in their operations. Some of the proposed converters contain constraint in their performance as the converter in Lavanya et al 21 Voltage of the main source and voltage of the battery in Lavanya et al 21 should have close values due to parallel connection between them in discharging mode. In Zhu et al, 22 a TPC with two unidirectional ports and many components is presented that has constraint in applications consisting of battery.…”

This paper presents a three‐port DC‐DC converter for photovoltaic (PV)/battery stand‐alone systems. The converter is designed by an effective combination of quadratic boost converter and a bidirectional port with low number of components. The converter performance consists of four operation modes with similar voltage gains, which improve reliability of the converter in comparison with the reviewed converters. Battery‐alone mode is performed in the proposed configuration for the times input power of PV is equal to zero. Main advantages of the converter include its common grounded ports, operation with high voltage gain, current continuous of the input ports, utilizing low number of switch to perform four essential operation modes, and its high‐efficiency performance due to low number of used components. Three switches of the structure enable it to control input power of main source and output voltage with two duty cycles per the modes. This number of switches in a three‐port converter requires simpler driving and control systems in comparison with some of the previous presented three‐port converters. The converter is analyzed, and its main equations are obtained. To validate feasibility of the converter and investigate coordination of its performance with theory, a prototype is prepared for 120 W output power.

A hybrid renewable energy system with more than one source like solar photovoltaic, wind energy, battery, and fuel cell increase the system’s reliability and flexibility. A suitable power electronic converter is required to integrate these sources and interface with the load simultaneously. Therefore, the paper’s main objective is to recommend a novel double input dc converter for a hybrid renewable energy system. This power electronic converter efficiently integrates the sources and supplies the load demand. The critical waveforms for various modes of operation of the proposed converter are discussed in detail and the output voltage equation is derived. The proposed double input converter has a simple structure and reduced components. The performance comparison with the currently reported converters in the literature is presented, and the double input converter is simulated and analysed using MATLAB/Simulink software. The theoretical analysis is validated through the simulation results of the designed double input dc converter for renewable energy application.
