“…Other control techniques are as follows: The paper [ 77 ] presents a two-stage microinverter and it consists of dc-dc triple active bridge (TAB) converter that integrates back-up battery; and the second stage is a voltage source inverter (VSI) that operates in both grid-connected mode (GCM) and stand-alone mode (SAM). The control algorithm consists in a central control based in a mode transition scheme.…”

The use of renewable energies sources is taking great importance due to the high demand for electricity and the decrease in the use of fossil fuels worldwide. In this context, electricity generation through photovoltaic panels is gaining a lot of interest due to the reduction in installation costs and the rapid advance of the development of new technologies. To minimize or reduce the negative impact of partial shading or mismatches of photovoltaic panels, many researchers have proposed four configurations that depend on the power ranges and the application. The microinverter is a promising solution in photovoltaic systems, due to its high efficiency of Maximum Power Point Tracking and high flexibility. However, there are several challenges to improve microinverter’s reliability and conversion efficiency that depend on the proper control design and the power converter design. This paper presents a review of different control strategies in microinverters for different applications. The control strategies are described and compared based on stability, dynamic response, topologies, and control objectives. One of the most important results showed that there is little research regarding the stability and robustness analysis of the reviewed control strategies.

“…Additionally, it has the advantage of obtaining an equivalent inductance value four times higher than the individual value of each one, considering that the inductance value of each coil is the same. The inductance value of an inductor, L, depends on the number of turns, N, and on parameters related to its construction, such as the cross-section area, A, the length of the core material, l, and the permeability of the material, µ 0 , Equation (20).…”

New Multifunctional Isolated Microinverter with Integrated Energy Storage System for PV Applications

This paper proposes a novel multifunctional isolated microinverter which is able to extract the maximum available power from a solar photovoltaic module and inject it into the power grid, while simultaneously charging a battery energy storage system (BESS). The proposed microinverter integrates a novel DC–DC power converter and a conventional DC–AC power converter. The DC–DC power converter is able to send electrical energy to the secondary side of a high-frequency transformer and to the BESS, using only two power switches. Throughout this paper, the converter topology, the operation modes, the control algorithms, and the development of a laboratory prototype of the proposed microinverter are described in detail. Moreover, simulation and experimental results are presented to demonstrate the feasibility of the proposed solution.
