摘要： The present invention relates an NPC switching device (10) for an X-ray system (86) with symmetric power supply, wherein the switching device is amended by extra damping resistors (13, 18) in the high voltage rails (24, 28). These resistors act as damping resistors. Thus, they may provide particular damping in combination with the load (100), which is capacitive dominated. Further, an additional inductor (77) may be provided at the output (48) of the NPC switching device allowing a resonant transition. In case the NPC switching device is connected with a grid capacitance of the X-ray system, comprising a cathode (90) and a grid (92), wherein the cathode and the grid form a grid capacitance, overshoot and settling time in the switching device may be controlled and reduced, in particular to a minimum.

摘要： Pre-conditioners (or line-conditioners) are used to convert electrical power having first characteristics into electrical power having second characteristics. For example, a pre-conditioner may connect electrical equipment forming a load, which requiring only a conventional mains supply level to a utility three-phase supply. This means that the power components of the load may be de-rated, making the load electrical equipment cheaper. Such circuits may be further improved. Components in the down-converter itself still need to be rated to interface with the higher voltage. An approach is proposed in which two interleaved down-converters (36, 38) can be used to supply voltages. An energy recovery element (50) connects snubbers of the interleaved down-converters, thus enabling some de-rating of the pre-conditioner circuitry.
