Abstract
An output stabilization circuit includes: a primary-side circuit including first and second self-excited oscillator circuits connected to a direct-current power supply; and a secondary-side circuit, wherein the first and second self-excited oscillator circuits include power transmission coils, resonant capacitors, switching element pairs, and feedback coils, the second self-excited oscillator circuit further includes a phase shift filter, the phase shift filter includes a primary-side control coil that is magnetically coupled to a secondary-side control coil included in the secondary-side circuit and that has a characteristic that an inductance changes depending on a current flowing through the secondary-side control coil.
