Abstract
The modern world demands more and more electric energy. At the same time, almost a billion more people are expected to gain access to electricity over the next decade. All of the above compose a very challenging future, where a continuously increasing amount of electric energy will be needed. However, the planet is not able to provide us anymore with the necessary resources for that, jeopardizing the environmental stability. The aim of this thesis is the design and testing of power electronics converters that will contribute positively to the production and distribution of sustainable energy. In particular, a Maximum Power Point Tracking Converter is designed and tested. The 6.4kW converter is able to connect to two separate PV strings. The output of the converter is connected to a bipolar DC distribution grid. Afterwards, a 3.68kW Voltage Balancing Converter was designed for the stabilization of the voltage between the two phases of a bipolar DC grid. Particular interest is given to the challenges that arouse for the power supply of a DC Micro-Grid from a Photo-Voltaic plant. The project took place in the DC lab of the company DC Opportunities.
