Converter system and wind or water turbine

摘要

The system has a rectifier (1) supplied with energy over an alternating current source (3) and connected with inverters (2) over a common direct current circuit (4) for supplying energy to the inverters. The inverters are connected with an electrical load e.g. direct current motor, for supplying energy to the load. A decoupling device (6) is arranged in a connection between the direct current circuit and one of the inverters, and comprises a diode. The decoupling device inhibits the transmission of electrical energy from the inverters to the direct current circuit. An independent claim is also included for a wind or water power plant.
