Claim:
1. A DC-DC converter circuit arrangement comprising: a first multiphase DC-DC converter for transporting energy between two electrical systems, said first multiphase DC-DC converter including at least two converter circuits, whereby each converter circuit features at least one first control element that can be regulated, and a controller that is capable of producing at least two drive signals, whereby the drive signals have different phases and operation of one of the at least two converter circuits of the first multiphase DC-DC converter can be controlled with each drive signal, at least a second multiphase DC-DC converter for transporting energy between two electrical systems, said second multiphase DC-DC converter including at least two converter circuits, whereby each converter circuit features at least one first control element that can be regulated, wherein the switched mode operation of each converter circuit of said at least one of said second multiphase DC-DC converter can be controlled by means of at least one of said drive signals, which can be produced by the controller, wherein the controller enables or disables the energy transport by means of the multiphase DC-DC converters; and wherein at least one second control element is arranged in series between to each multiphase DC-DC converter and both of the electrical systems, whereby the second control elements can be operated to close or to open by means of the controller in order to enable or disable the energy transport.
