More Information
Summary:In a resonance DC/DC converter, an input circuit has a configuration including a DC power source, a resonance auxiliary coil, a primary-side coil, a switching element connected in series, and a rectifying element and a resonance capacitor connected to the switching element in parallel. Here, there are provided an inductance value shifting circuit configured to shift an inductance value of the resonance auxiliary coil, and a control device configured to control the inductance value shifting circuit and shift the inductance value of the resonance auxiliary coil in accordance with a voltage value of the DC power source so that a voltage across the primary-side coil becomes constant.
