Regardless of its type and size, any organization is faced with risks that can affect the achievement of its objectives in terms of activities, strategic initiatives, operations, processes and projects, with different consequences on strategic, operational, financial results and image and reputation. All activities of an organization involve risks, and risk management is the process of substantiating the decision, by taking into account the effects of uncertainty on the materialization of objectives and determinin...

The conversion of the solar energy depends mostly on the irradiance of the Sun at the level of the photovoltaic panel. Another significant factor that modifies the solar energy conversion is the temperature at the surface of the PV panel. The energy output of the Sun is fairly constant, but the solar irradiance varies significantly from one hour to another and changes throughout the day. In this paper we are presenting the design of a simple but effective MPPT (Maximum Power Point Tracker) charge controller based ...

MATLAB APPLICATIONS IN THE STUDY OF CONNECTION SCHEMES OF INDUCTIVE CIRCUITS TO ALTERNATIVE CURRENT SOURCES

(STEF92 Technology, 2017-06-20, Titu Niculescu, Marius Marcu, Florin Popescu, Razvan Slusariuc)

In industrial electric installations there are situations when inductive circuits are connected to AC power sources. These operations are accompanied by the appearance of specific transients after which may occur overvoltage spikes that can become dangerous for components in the circuit. Evaluation of these surges and other electrical specific parameters are the subject of this paper. Measurement method is based on using a data acquisition system produced by National Instruments and MATLAB is used as software envi...
