Title:
A STEP-FREE INDUCTION CONTROLLED VOLTAGE REGULATOR
Document Type and Number:
WIPO Patent Application WO1999017314
Kind Code:
A3
Abstract:
A step-free induction controlled voltage regulator, primarily for high-voltage regulation, includes a magnetic circuit based upon a magnetizable core (1) having one or more flux paths or legs (2) with at least one winding (3) supplying the output voltage (U). The output winding leg (2) includes a regulation arrangement (4-8) comprising a rotatable rotor means (4) carrying a regulator winding (6) electrically connected in series with the output winding (3). A compensator winding (7) can be arranged around the leg (2) and electrically connected in series with a capacitor means (8). At least one of the regulator winding (6) and the supply winding (3), or a part thereof, is wound by a high-voltage cable comprising at least one conductor surrounded by a first layer having semiconducting properties, a solid insulating layer, and a second layer having semiconducting properties.
