Abstract
A DC/DC converter includes: a first connection pole and a second connection pole, wherein a first DC voltage is applied between the first connection pole and the second connection pole; a third connection pole and a fourth connection pole, wherein a second DC voltage is applied between the third connection pole and the fourth connection pole; a first commutation cell, wherein the first commutation cell has a capacitor, a diode and a semiconductor switch; a second commutation cell, wherein the second commutation cell has a capacitor, a diode and a semiconductor switch; and a precharging circuit for precharging the capacitor of the first commutation cell and the capacitor of the second commutation cell. The precharging circuit has a precharging resistor and an actuable switching device. The precharging resistor and the actuable switching device are connected in parallel. The capacitor of the first commutation cell, the precharging circuit and the capacitor of the second commutation cell are looped in series between the first connection pole and the second connection pole.
