Abstract
A high frequency power supply circuit for supplying energy to a parallel resonant tank circuit and including a pair of serially connected capacitors having a common terminal connected to the load. The other capacitor terminals are respectively connected to the load through saturable reactors. A substantially constant current bias supply circuit is connected across the other terminals of the reactors and polarized in a manner to produce current flow through the reactors in a direction opposite to that produced by the capacitor discharge. The saturable reactors may comprise a plurality of annular core members disposed on an elongate tubular conductor. Alternatively the reactors may comprise a plurality of core members having an axially extending toroidal winding therearound.
