Magnetically controllable choke coil having central connection

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

• at least one high-voltage connection configured to be connected to a respective phase conductor;
• and
• for each high-voltage connection:
• a first and a second core sections being part of a closed magnet circuit;
• at least one saturation switching branch configured to saturate at least one of said first and second core sections, said at least one saturation switching branch having controllable power semiconductor switches;
• a first high-voltage winding enclosing said first core section;
• a second high-voltage winding enclosing said second core section and being connected parallel to said first high-voltage winding;
• at least one of said first and second high-voltage windings having a central connection connected to said high-voltage connection and winding ends connected to said at least one saturation switching branch;
• and
• a control unit for controlling said power semiconductor switches.
