A system for compensating for a back emission current in an X-ray generator is provided. The system includes a transformer, a common, and a voltage source. The transformer is operative to provide power to an electron emitter of the X-ray generator. The common is electrically coupled to an anode of the X-ray generator. The anode is operative to receive electrons emitted by the electron emitter such that the back emission current is generated between the common and the electron emitter. The voltage source electrically couples the common to the transformer and is operative to generate an offset voltage that reduces the back emission current.

System and method for compensating for back emission current in an X-ray generator

A switch of an inverter of an X-ray tube power supply including: at least four MOSFETs aligned in parallel; a plurality of intermediate radiators positioned between the MOSFETs in order to separate two successive MOSFETs; at least four snubbers positioned in parallel, each being positioned beside a MOSFET; a control unit of said switch positioned so that the succession of MOSFETs is positioned between the alignment of snubbers and the control unit.
