Algorithm for online coefficient correction artificial neural network in MPPT controllers for solar batteries.

Trudy Odesskogo Politehničeskogo Universiteta, 2023
The main element of solar power plants is usually a power cascade (DC/DC converter, inverter). Converters in such generation systems should have high efficiency (at least 90%), high output signal quality and ensure operation of the power plant with ...

Nonlinear models of power inductors: A survey

International Journal of Circuit Theory and Applications, Volume 50, Issue 1, Page 2-34, January 2022., 2022
Power inductors are usually modeled as linear components. Here, we review nonlinear behavioral models of power inductors working, at least partially, in magnetic saturation. We discuss the pros, cons, and ranges of validity of these models, focusing on their application to simulation, design, monitoring, and control of switch‐mode power supplies ...

DC/DC Modular Multilevel Converters for HVDC Interconnection: A Comprehensive Review

International Transactions on Electrical Energy Systems, Volume 2022, Issue 1, 2022., 2022
High voltage direct current (HVDC) technology is a key component in power systems owing to huge benefits such as long‐distance power transmission, lower losses, asynchronous grid interconnections, controllability, system availability, and limited short‐circuit currents.

Coordinated Control of an Islanded Microintegrated Energy System with an Electrolyzer and Micro‐Gas Turbine

International Journal of Photoenergy, Volume 2022, Issue 1, 2022., 2022
Microintegrated energy systems (MIESs) can be disconnected from power distribution systems during power system faults. This paper develops a control scheme for an islanded MIES. The VSC inverter controls the AC bus voltage and frequency using a modified AC voltage regulator and a modified frequency regulator.

An improved 24‐pulse rectifier for harmonic mitigation in more electric aircraft

IET Power Electronics, Volume 14, Issue 11, Page 2007-2020, 19 August 2021., 2021
Abstract To increase the power rating and reduce the cost and complexity of a multi‐pulse rectifier (MPR), it is well known that the pulse number must be increased. In some practical cases, a 12‐pulse rectifier (12PR) is suggested as a good solution considering its relatively simple structure and low weight.

Exploiting buck–boost duality in dual active bridge modular multilevel converters to achieve high DC step ratios

High Voltage, Volume 6, Issue 3, Page 495-513, June 2021., 2021
Abstract A previously unidentified duality between buck and boost configured dc‐ac modular multilevel converters (MMCs) is firstly revealed. Armed with this insight, a new dual‐active‐bridge (DAB)‐MMC is proposed for high‐voltage dc (HVDC)‐to‐medium‐voltage dc (MVDC) power conversion that utilizes cascaded buck and boost dc–ac stages to obtain high dc ...

Seamless control for single‐phase high gain quasi‐switched impedance source multilevel inverter for distributed generation application

IET Power Electronics, Volume 14, Issue 5, Page 969-981, 8 April 2021., 2021
Abstract The single‐stage buck‐boost multilevel inverters are getting more attention even in low‐voltage and low power distributed generation applications due to high reliability with shoot‐through invulnerability. But the inherent boosting ability of most of the inventions is constrained by the device stresses and deprived performance at a low ...
