This article presents an overview of different transformer-less single-phase grid-connected photovoltaic inverters with various filter circuits including immittance conversion topology for residential application. Various inverter topologies are presented, compared, and evaluated against components used, size, cost, self life, losses, and efficiency. To find the suitable topology, a number of factors...
In Bangladesh, approximately 3900 square miles of entire length is surrounded by 700 rivers including tributaries. Around 770,000 inland and 510,000 marine fishermen survive in this country, whose income entirely depends on fisheries. Bangladeshi fishermen mainly use trawler for fishing purpose in sea and river. Those trawler boats require electric power at night for fishing and lighting purposes...
This paper discusses the Life Cycle Cost Analysis (LCCA) of a fishing trawler using solar energy to be installed in the Bay of Bengal in Bangladesh. This system is entirely green, free and economically feasible solution for a fishing trawler for cultivating fish in Chittagong region of Bangladesh. The Life Cycle Cost Analysis of this proposed design is mathematically modeled via software. The LCCA...
The paper proposes an up to date design and simulation of a grid connected photovoltaic system using Simulink. A Photovoltaic (PV) cell, a DC/DC boost converter and a DC/AC inverter constitutes the system. The internal mechanism of solar cell with diagram & approximation of PV cell are described. The PV cell model is simple, precise, and takes external temperature as well as solar radiation into...
