Abstract :
A high-speed 1600 kW permanent-magnet generator is being developed. The generator is designed to run directly from a gas turbine without a gearbox. The 600 Hz generator frequency is rectified by means of 6-pulse diode bridges. Connection to 50 Hz (60 Hz) mains frequency in the case of decentralized power generation is achieved by means of a power electronic converter based on a special interlaced technique with two 300 kVA IGBT stacks paralleled by means of an interphase transformer. A 500 kW (600 kVA) TWIN converter module with interphase transformer has been designed, built and tested. Details concerning the practical design aspects and the system control are given
