Abstract
A bootstrap compensation circuit includes: a plurality of resistors series-connected between a floating potential corresponding to a high-voltage-side potential and a reference potential; a second capacitor that has one end connected to a divided potential extraction point and has the other end connected to the reference potential, the divided potential extraction point located between the plurality of resistors; and an output circuit which supplies current to a first capacitor, according to a potential of the divided potential extraction point.
