EN In this chapter, the elaborated structures of the main circuit and control system of a power electronics AC/DC/AC converter, working as a coupling between the energy grid and a water turbine with an electric machine, are described. In aiming to ensure the high efficiency of this system, input and output converters with sinusoidal current were implemented. The input AC/DC converter is based on a diode rectifier with a power electronics current modulator in the DC circuit, while the output circuit is based on a transistor inverter. This solution is dedicated to high power systems. The chapter also presents an MPPT algorithm, which is elaborated and used to control the DC/DC converter. The chosen simulation and experimental results of the research is analysed.
