摘要： A static electromagnetic frequency changer utilizes linear inductances and capacitances and a saturable reactance to generate subharmonic frequencies. The magnetic components of the circuit are designed to be combined on a single magnetic structure. The frequency changer is rendered relatively insensitive to slight changes in the frequency and amplitude of the driving signal through the inclusion of a feedback winding.

摘要： A circuit for controlling the harmonic currents in the secondary windings of saturable core transformers used to supply power to induction furnaces. Switching means are provided whereby the primary and tertiary windings of the saturable core transformers are selectively connected in Y-Y or in series Y. When connected in Y-Y, the core is saturated and significant harmonic currents are induced in the series connected secondaries. When connected in series Y, the cores are driven out of saturation and only negligible harmonic currents exist in the series connected secondaries.

摘要： There is disclosed a frequency multiplying device for induction heating applications in which the supply voltage is applied between two central taps of a heating inductor and a saturable reactor. The extremities of the saturable reactor are connected to those of a resonant circuit constituted by the heating inductor and a condenser in parallel therewith, through impedances such that the currents at supply frequency traversing them are of equal value and of symmetrical phases with respect to the phase of the supply voltage, the angle of each such phase being equal to 90* divided by the selected frequency multiplier and multiplied by an odd integer, so that these currents are in phase operation and their sum is nil.
