Abstract:
An interface arrangement for coupling between an AC system and a DC system. The arrangement includes a converter for conversion between AC and DC and having a DC side with a first and a second terminal for connection to the DC system and an AC side with a group of terminals for being coupled to the AC system, a transformer having a primary side with a first set of primary windings for being coupled to the AC system and a secondary side with a second set of secondary windings coupled to the converter, where the transformer is equipped with a third set of auxiliary windings and a short-circuiting device is connected between the third set of auxiliary windings and ground.
