In our days with the decrease of primary stocks and environmentally friendly lifestyle, there is a need to use secondary energy sources. In the foreseeable future a big growth is expected in the number of solar cells, in the amount of energy, which can be produced by the solar cells.

Sometimes the solar cells produce more energy than the user need, in this case the user will be an energy supplier for the energy network. In my thesis I will plan an iverter, which can convert the direct current produced by the solar cell into alternate current, which has the same amplitude and frequency as in the energy network is available.

In the first part of my thesis I show how a DC/DC converter and inverter works; what were the boundary conditions to choose the hardware parts; I present detailed the most important parts of the schematic; I demonstrate how the printed circuit board was planned.

In the second part I present the software, which I wrote to control the inverters and the boost converte. Besides this, I present the user interface, and what kind of parameters can the user adjust, how the inputs and outputs were set, how current and voltage is measured.
