Claim 0:
1. A DC/DC converter, comprising:
a first connection pole and a second connection pole, wherein a first DC voltage is present 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 present between the third connection pole and the fourth connection pole;
a first switching cell, wherein the first switching cell has a capacitor, a diode and a semiconductor switching device;
a second switching cell, wherein the second switching cell has a capacitor, a diode and a semiconductor switching device; and
a precharging circuit for precharging the capacitor of the first switching cell and the capacitor of the second switching cell, wherein the precharging circuit has a precharging resistor and a driveable switching device, wherein the precharging resistor and the driveable switching device are connected in parallel,
wherein the capacitor of the first switching cell, the precharging circuit and the capacitor of the second switching cell are wired in series between the first connection pole and the second connection pole.
