Beschreibung
Zusammenfassung:	In this DC/DC converter, a first controller calculates a first operation value on the basis of a difference between output voltage Vout and a first calculated value calculated on the basis of a detection value of voltage of the charge/discharge capacitor. A second controller calculates a second operation value on the basis of a difference between a charge/discharge capacitor voltage target value Vcf* and charge/discharge capacitor voltage Vcf. In control blocks, addition and subtraction of the first and second operation values are performed, and the conduction rates for switching elements are controlled, to control the output voltage and a charge/discharge capacitor voltage, thereby preventing application of overvoltage to the switching elements.
