Abstract
The apparatus for non-contacting feeding of a high frequency power according to the present invention comprises a double voltage full-wave rectifier circuit which converts an AC input into a DC output, Royer oscillation circuit consisting of FETs and which receives the DC output from the voltage double full-wave rectifier circuit and provides a high frequency oscillation, the gate windings ofhe FETs being the second winding of a saturable circuit, a starting gate bias stabilization circuit for the Royer oscillation circuit, and a main transformer which delivers a high frequency power produced in the Royer oscillation circuit, through the primary winding of the oscillation-use saturable transformer.
