In my thesis I have dealt with the regulation of solar inverters which produces on single-phase household electric networks.

In the introduction I have introduced the solar panel-based output converter systems, described the operation of the solar panels and the common solutions on how to feed the produced energy into the consumer network.

In the second chapter I have described the possibilities of the regulation of solar inverters, dealt with effects of common mode current occurring in one-phase solar systems. I have also shown two methods for compensating the effects of one-phase power production. Additionally I have shown the results of the simulations serving to compare the effectiveness of these two methods. During the simulation I have tested the controller’s static and dynamic behavior and the quality of the output current.

I have tried the above-mentioned methods on a small power inverter producing for a single-phase network. In the third chapter I described the results of these measurements.

In the last chapter I have briefly rated the results.
