Abstract
According to an embodiment, there is provided an apparatus which can hold down an energy loss and can avoid an increase in size. The apparatus includes a cell including a floating capacitor connected in parallel to an upper-side switching element and a lower-side switching element; an upper arm include including first switch circuits, each including a first switching element, a first diode and a first capacitor, are connected in series; a lower arm including second switch circuits, each including a second switching element, a second diode and a second capacitor, are connected in series; and a circuit which connects a low-side terminal of the cell and a low-side terminal of the first capacitor and connects a high-side terminal of the cell and a high-side terminal of the second capacitor.
