Re: DC Controlled Reactance Choke
This concept works very well. We use it in our reactors for higher powered
coil systems. Using a gapped core E-I reactor you wind approx 150 turns
around the center of the E lamination and then wind your normal reactor
windings over this. By running approx 75-100 VDC at 3-5 amps through the
center winding you have complete control over the reactor's performance.
