Abstract
A DC-to-DC converter includes a first capacitor, first, second, third, and fourth switches connected in series between first and second electrodes of the first capacitor, a second capacitor connected to a connection node of the first switch and the second switch and a connection node of the third switch and the fourth switch, an inductor connected to a connection node of the second switch and the third switch, and a controller that controls an on/off state of each of the first to fourth switches on the basis of a value obtained by applying a reciprocal of a detection current that is a measured current flowing through the inductor to a difference between a first detection voltage and a first voltage instruction value and a difference between a second detection voltage and a second voltage instruction value.
