ABSTRACT:
A self-oscillating inverter uses saturable transformer means in its positive feedback circuit. The saturation flux density of the magnetic material used in this saturable transformer means determines the frequency of inverter oscillation. A permanent magnet is rotatably mounted proximate to the saturable transformer means and is used for adjustably affecting the saturation flux density of the magnetic material, thereby correspondingly to adjust the frequency of oscillation: the stronger the magnetic flux provided to the magnetic material from the permanent magnet, the smaller the saturation flux density and the higher the frequency of oscillation.
