An Improved Harmonics Mitigation Scheme for a Modular Multilevel Converter
A. Rakesh Kumar,Mahajan Sagar Bhaskar,Umashankar Subramaniam,Dhafer Almakhles,Sanjeevikumar Padmanaban,Jens Bo Holm Nielsen +5 more
TL;DR: An improved harmonics mitigation scheme for a Multilevel DC-Link Inverter (MLDCLI), which is a variant of MMC, is proposed, a modified version of the conventional Nearest Level Modulation (NLM) scheme, termed as modified Nearest level Modulations (mNLM).
Journal ArticleDOI
A Sustainable Solar Photovoltaic Energy System Interfaced with Grid-Tied Voltage Source Converter for Power Quality Improvement
TL;DR: In this article, a photovoltaic (PV) array interfaced with a DC-DC boost converter feeding three-phase grid-tied voltage source converter is designed and modeled, and its performance is verified through simulation in MATLAB/Simulink.
Journal ArticleDOI
Exergy analysis of thin-film solar PV module in ground-mount, floating and submerged installation methods
TL;DR: In this paper, an exergy-based parametric approach is used to understand the realistic performance and the energy conversion process of the photovoltaic (PV) module in both water and land environments.
Journal ArticleDOI
Enhancement of Power Quality in Domestic Loads Using Harmonic Filters
P S Sanjan,N Gowtham,Mahajan Sagar Bhaskar,Umashankar Subramaniam,Dhafer Almakhles,Sanjeevikumar Padmanaban,N G Yamini +6 more
TL;DR: The study was carried out to identify a reference current extraction technique that yields the best performance and understand the implementation of the same to identify inherent issues that can sometimes be overlooked because of their simplicity and ease of implementation.
Journal ArticleDOI
Single phase nine level inverter using single DC source supported by capacitor voltage balancing algorithm
Rathinam Marimuthu Sekar,Dhanaraj Nelson Jayakumar,Kaliamoorthy Mylsamy,Umashankar Subramaniam,Sanjeevikumar Padmanaban +4 more
TL;DR: A new single phase nine-level inverter using two capacitors and a single DC source is introduced using two control algorithms namely charging algorithm and discharging algorithm to eliminate Voltage imbalances in the capacitors.
