Abstract
A flying capacitor device, such as an inverter arm or a boost converter, includes a plurality of N switching cells which are nested in one another and a balancing circuit which is adapted to have a resonant frequency equal to the switching frequency of the transistors. The balancing circuit is connected, on the one hand, at a midpoint and at a terminal of a capacitor of the last cell.
