CONVERTER SYSTEM AND WIND OR WATER POWER PLANT

The invention relates to a converter system, comprising a rectifier (1) and at least two inverters (2), wherein the rectifier (1) can be supplied with energy by an alternating-current source (3), the rectifier (1) is connected to each of the inverters (2) by means of a common direct-current circuit (4) in order to supply energy to the inverter (2), and each inverter (2) can be connected to a respective electrical load (5) in order to supply energy to the respective 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). The invention further relates to a wind or water power plant, comprising a rotor, wherein the rotor has a rotor hub and at least two rotor blades and the rotor blades can be rotated about the respective longitudinal axes thereof 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 has a converter system according to one of the claims 1 to 11, wherein the converter system supplies the loads (5) with energy.
