Shortcoming: passive filter can only filter out the harmonic wave of specific order, the harmonic wave of residue order can cause severe jamming.
Measure 4: several controlled winding additional on magnetic element, with special inverter to a controlled winding input controllable AC electric current, residue controlled winding connects thyristor and the current-limiting inductor thereof that inverter connects a pair reverse parallel connection respectively, changes the inductance value of magnetic element by the way that the conduction angle of each thyristor matches with inverter controllable AC electric current.
Shortcoming: too complicated, hidden failure point is too many.
Measure 5: regulate magnetic element magnetic core air gap to change the magnetic resistance of main magnetic circuit.
Shortcoming: iron core air gap is difficult to accurate control, can effectively regulate the yardstick of air gap very little, and continuous stepless regulates and is difficult to accomplish, powerful magnetic element air gap is along with noise, vibration and electromagnetic interference (EMI).
Therefore, how overcoming above-mentioned shortcoming, carry out directly magnetic resistance, regulating continuously and is on a large scale object of the present invention.
