Magnetically controllable throttle for reactive power compensation having capacitively connected auxiliary windings

A device for reactive power compensation in a high-voltage grid having at least one phase conductor, the device comprising:

• at least one high-voltage terminal configured for connecting with the at least one phase conductor;
• core sections including a first core section and a second core section being elements of a closed magnetic circuit;
• high-voltage windings including a first high-voltage winding enclosing said first core section and a second high-voltage winding enclosing said second core section and connected in parallel with said first high-voltage winding;
• at least one saturation switching branch configured for a saturation of said core sections and having actuatable power semiconductor switches;
• a controller for actuating said actuatable power semiconductor switches;
• said first high-voltage winding and said second high-voltage winding each having a high-voltage end connected to said at least one high-voltage terminal and, a low-voltage side connected to said at least one saturation switching branch;
• at least one capacitively acting component;
• and
• auxiliary windings inductively coupled to said high-voltage windings, said auxiliary windings being interconnected with said at least one capacitively acting component.
