Abstract (en)
[origin: WO2016034232A1] A test circuit (100, 200) for a voltage-regulated power converter module (2) in power converters (6, 10, 206, 210) for high-voltage direct current transmission, comprising a first power converter (6, 206) with an alternating current connection (20) and a first and a second direct current connection (22), wherein the alternating current connection (20) in the first power converter (6, 206) is connected to the first direct current connection (22) via a first series (32) of voltage-regulated power converter modules (2), wherein the alternating current connection (20) in the first power converter (6, 206) is connected to the second direct current connection (22) via a second series (32) of voltage-regulated power converter modules (2), further comprising a second power converter (10, 210) with an alternating current connection (20) and a first and a second direct current connection (22), wherein the respective first direct current connections (22) are connected to each other and the respective second direct current connections (22) are connected to each other, which should enable a test of voltage-regulated power converter modules independent of the network frequency and using alternating and direct current load. In addition, the respective alternating current connections (20) are connected to each other via an inductance (104).
