Abstract
A magnetic-coupling multivibrator has a rectification circuit including first and second smoothing capacitors connected at a capacitor common junction, the first smoothing capacitor providing a high potential output, the second smoothing capacitor providing a low potential output. A switching series circuit has first and second switching elements connected in series at a common switching junction, the switching series circuit being connected in parallel to the smoothing capacitors. A first saturable transformer has a first saturation coil, a first control coil and a first gate drive coil, and a second saturable transformer has a second saturation coil, a second control coil and a second gate drive coil. A first gate control circuit interfaces the first gate drive coil with the first switching element to effect turn on and off and a second gate control circuit for interfacing the second gate drive coil with the second switching element to effect turn on and off alternately with turn on and turn off of the first switching element to effect continuous oscillation. A current source for driving the first and second control coils to control saturation of the first saturable transformer a…
