“…The voltage-source converter consisted of two IGBT bridges for low-rising harmonics. The voltage source and DC-DC copper converter were connected to each other with a DC-link capacitor [27,28]. The voltage-source converter provided an electronic power intermediary between the AC power system and the superconductor coil.…”

In conventional low-voltage grids, energy-storage devices are mainly driven by final consumers to correct peak consumption or to protect against sources of short-term breaks. With the advent of microgrids and the development of energy-storage systems, the use of this equipment has steadily increased. Distributed generations (DGs), including wind-power plants as a renewable energy source, produces vacillator power due to the nature of variable wind. Microgrids have output power fluctuations, which can cause devastating effects such as frequency fluctuations. Storage can be used to fix this problem. In this paper, a grid-connected wind turbine and a photovoltaic system are investigated considering the atmospheric conditions and wind-speed variations, and a control method is proposed. The main purpose of this paper is to optimize the capacity of energy-storage devices to eliminate power fluctuations in the microgrid. Finally, the conclusion shows that, in microgrids with supercapacitors, the optimal capacity of microgrid supercapacitors is determined. This method of control, utilizing the combined energy-storage system of the battery supercapacitor, in addition to reducing the active power volatility of the wind turbine and photovoltaic generation systems, also considers the level of battery protection and reduction in reactive-power fluctuations. In the proposed control system, the DC link in the energy-storage systems is separate from most of the work conducted, which can increase the reliability of the whole system. The simulations of the studied system are performed in a MATLAB software environment.

“…[18] have developed a high‐gain multiport DC–DC converter with a non‐isolated structure without any coupled‐inductor. The voltage growth ratio of this converter is higher than [11–16], but it has a lower voltage gain than the proposed converter. In spite of the truth that the voltage lift ratio per number of devices in [18] is worthy, but the voltage lift ratio per number of devices is lower than the proposed converter in this paper.…”

This article offers a non‐isolated DC–DC converter with dual‐ports for input and dual‐ports for output with high step‐up ability. The converter has different levels of output voltage. The benefits of the proposed topology consist of the capability of giving high voltage gains with low duty cycle amount, the simple control of each duty cycle, and low per‐unit peak voltage stress (PPVS) over the semiconductors. The presented structure is suitable for clean energy applications. The operation principles, steady‐state analysis, voltage, and current equations extraction in continuous conduction mode (CCM) are carried out. To confirm the superiority of the proposed topology, the efficiency of the converter is compared to other multi‐input (MI) and multi‐output (MO) converters which were recently published in the literature. Eventually, an implemented prototype in the laboratory is used to verify the performance of the proposed structure.

“…The DIC uses three inductors, two energy transfer capacitors and two switches. In another application for unidirectional clean energy sources such as solar PV and fuel cell, a DIB converter topology with a three‐winding coupled inductor and two switches was implemented 9 . A simple DIC in Reference 10 used two inductors, two switches and one capacitor for energy transfer operation.…”

Summary Adaption of an on‐board solar PV system in electric vehicles (EVs) can cut pollution by reducing the demand from the grid. It eliminates the need of human intervention for charging EVs as well. Similarly, introducing wireless power transfer (WPT) for EVs cuts attendant requirements and charger chord handling. Therefore, charging a EV battery with combined power from the on‐board solar PV system and WPT using a dual‐input DC‐DC converter is introduced in this article. A small signal model of the dual‐input boost (DIB), dual‐input buck (DIBK) and dual‐input buck‐boost (DIBB) converters is derived. Transfer functions for all three converter operations are derived and used to design proportional integral (PI) controllers. The WPT source is considered a variable DC source, and a lead‐acid battery rated 120 V/165 Ah at 55% state of charge (SoC) is used as load in the simulation. Controller design and stability analysis are discussed in detail. The hardware experimentation of a developed combined charging system test bench is performed with resistive load and 10 nos. of lead‐acid battery stack, each rated 12 V/20 Ah. The performance of DIB and DIBB converter modes under continuous conduction is studied with a detailed loss analysis of the WPT system and dual‐input converter (DIC). Also, the proposed integrated system is compared with various integrated DIC topologies.
