    • In a switching regulator, a power feed circuit section includes a reactor, a capacitor, and a switching circuit controlling power supply from a power supply source to the reactor. A reference command value generation portion generates a reference command value based on a physical quantity representing a state of the power feed circuit section. An adder adds a pseudo command value depending on a reactor current flowing in the reactor to the reference command value. A limiter limits at least one of an upper limit value and a lower limit value with respect to an adding result of the adder. A removing section removes a value corresponding to the pseudo command value from a processing result of the limiter. A control performing section controls a duty ratio of the switching circuit using a processing result of the removing section as a command value.

    • In a switching regulator, a control circuit includes a reference command value generation portion and an additional command value generation portion. The reference command value generation portion generates a reference command value based on a deviation of an output voltage from a predetermined command voltage. The additional command value generation portion generates an additional command value based on a difference between an outflow electric energy and an inflow electric energy. The outflow electric energy is a value reflecting a supply power from the capacitor to the load, and the inflow electric energy is a value reflecting a supply power from the reactor to the capacitor. The control circuit controls an operation ratio of a switching circuit based on the reference command value and the additional command value.

    • In a power converter, at least two main current paths each including an inductor and a transistor are connected between input terminals, and at least two storage circuits each including capacitors are correspondingly connected to branch nodes of the main current paths. Diodes are connected between the storage circuits. The transistors of the main current paths are interleaved.
