<p>The method involves performing a regulated or controlled, network synchronous transformer (3) magnetization using system parameters such as the network voltage and current and the input current of a pulse current converter (8) suitable for four quadrant operation connected to at least one secondary winding (5.1) of the transformer, whose primary winding (4) is connected to the a.c. voltage network (1) via a power switch (2). An Independent claim is also included for a circuit for connecting a transformer to an a.c. voltage network.</p> |
