Switching regulator

A switching regulator comprising:

• a power feed circuit section including a reactor, a capacitor, and a switching circuit, the reactor connected to a power supply source, the capacitor connected between two output terminals, the capacitor charged and discharged by electric current supplied from the reactor, the switching circuit controlling power supply from the power supply source to the reactor;
• a reference command value generation portion generating a reference command value based on a physical quantity representing a state of the power feed circuit section;
• an adder adding a pseudo command value depending on a reactor current flowing in the reactor to the reference command value;
• a limiter limiting at least one of an upper limit value and a lower limit value of an adding result of the adder;
• a removing section removing a value corresponding to the pseudo command value from a processing result of the limiter;
• and
• a control performing section controlling a duty ratio of the switching circuit using a processing result of the removing section as a command value.
