CONVERTER SYSTEM AND WIND OR WATER POWER PLANT

A converter system with a rectifier (1) and at least two inverters (2) is described and depicted, wherein the rectifier (1) can be supplied with energy from an alternating current source (3), the rectifier (1) is connected to each of the inverters (2) via a common direct voltage circuit (4) in order to supply energy to the inverters (2) and each inverter (2) can be connected to a respective electrical load (5) in order to supply energy to the respective electrical load (5). According to the invention, a converter system that is especially reliable is realized in that a decoupling device (6) is arranged in at least one of the connections between the direct current circuit (4) and one of the inverters (2), wherein the decoupling device (6) prevents electrical energy coming from the inverter (2) from being transmitted in the direction of the direct current circuit (4). A wind or water power plant with a rotor is also described and presented, wherein the rotor comprises a rotor hub and at least two rotor blades and the rotor blades can be rotated about their respective longitudinal axes by electrical loads (5). According to the invention, a wind or water power plant that is especially reliable is realized in that the wind or water power plant comprises a converter system according to one of the claims 1 through 11, wherein the converter system supplies the loads (5) with energy.
