CHANGE OF FREQUENCY CHARACTERISTICS OF A FILTER USING A REACTOR WITH SMOOTHLY ADJUSTABLE INDUCTANCE

Experimental studies of the proposed reactor by the authors were carried out through direct measurements of electrical quantities. Structurally, the reactor is designed as a stator of an electric machine with a single pair of poles and a rotor without windings in the form similar to an elliptical shape with flat sides. The magnitude of the inductance varies by rotating the rotor within the range from zero to ninety degrees, where zero degrees corresponds to the alignment of the stator pole axis with the longer axis of the rotor. The effectiveness of using such a reactor to complement passive controlled harmonic current filters is confirmed by corresponding calculations. It is shown that one controlled filter can replace two or more precisely tuned filters capable of absorbing only certain current harmonics.

Keywords:

electric reactor, smooth adjustment of reactor inductance, passive harmonic and interharmonic current filter
