Design methodology and implementation of an all SiC power semiconductor-based, grid-connected multi-string photovoltaic (PV) supply with an isolated high frequency (HF) link maximum power point tracker (MPPT) have been described. This system configuration... see more

In the past decades, the inappropriate subsidy policies in many nations have caused problems such as serious oversupply, fierce competition and subpar social welfare in the photovoltaic (PV) industry in many nations. There is a clear shortage in the PV in... see more

Article Details: Received: 2019-07-11 | Accepted: 2019-10-03 | Available online: 2019-12-31 https://doi.org/10.15414/afz.2019.22.04.114-123Arbuscular mycorrhizal fungi (AMF) are often negatively affected in agro-systems. This investigation tested the hypo... see more

Solar power plants using environmentally friendly technology in the process of harvesting energy from the sun can be a solution to the future electricity crisis so that it has been the most widely developed and reliable alternative. However, the... see more

There are several types of photovoltaic system configurations, one of which is the on-grid PV system. This system is simple compared to other systems. Because there are two different energy sources that can supply the load either together or separately, a... see more

The Iraqi Kurdistan region has significant potential for implementing solar energy with an average annual rate of 5.245 kWh/m2. However, most of its energy supply currently comes from nonrenewable energy sources. With the continually increasing demand for... see more

Kualitas udara dalam ruangan merupakan faktor yang signifikan yang dapat mempengaruhi derajat kesehatan tenaga kerja. Buruknya kualitas udara dalam ruangan akibat keberadaan pencemaran udara (suhu, kelembaban, debu dan peralatan perkantoran) yang sangat b... see more

Während der dritten Reihenuntersuchung in der Freien und Hansestadt Hamburg an Aesculus spp. wurden 94 Rosskastanien der Arten A. hippocastanum und A. carnea auf die Phytopathogene Pseudomonas syringae pv. aesculi und Phytophthora spp. untersucht. Die Bäu... see more

Hybrid power system can be used to reduce energy storage requirements. In this paper, mathematicalmodels for characterizing Photovoltaic module, wind generator and battery are proposed.This paper presents the optimal size of an autonomous hybrid PV/wind e... see more
