Abstract:
A premagnetization device is disclosed for a converter system connectable to a three-phase electrical grid that has a three-phase power transformer, a converter connected to the power transformer and a circuit-breaker on the grid side of the power transformer. The premagnetization device is configured to suitably premagnetize the power transformer in a state isolated from the grid. The premagnetization device uses a single-phase reference voltage (Uref) that has a fixed relationship to the grid voltage (Ugrid) with regard to the voltage parameters, in order to generate, based on the measured instantaneous reference voltage (Uref) and the known fixed parameter relationships, by actuating the converter, a three-phase alternating voltage synchronous to the grid voltage (Ugrid) on the grid side of the power transformer. A converter system and a method for premagnetizing a three-phase power transformer of a converter system are also disclosed.

Claim (Index 2):
The premagnetization device according to  claim 1 , wherein the reference voltage (Uref) is a voltage derived from the grid voltage (Ugrid).
