37、m CP2-012 A simplified block diagram is shown in Fig 3.0. Single phase power is fed into aphase controller and then into an averaging filter comprising L and C. Control signals from the electronics vary the conduction angle of the phase controller to varythe D.C.voltage across capacitor C.The output
38、 EHT is directly proportional to the voltage across C and is controlled by it. It is marked, Controlled DC Line.The voltage is fed into a high frequency inverter which produces a sine wave drive (25 KHz) to the EHT step up transformer. Connected to the transformer is a 10 stage voltage multiplier pr

This voltage is fed via a standard European 160 kV high voltage receptacle and cable to the X-raytube.Common to the high voltage output is the filament drive voltage. This is an isolated supply which is controlled electronically to stabilise the beam current
40、 ofthe X-ray Tube against changes in theAC supply and the high-voltage output.The electronic control circuits are linked by an interface cable to the system electronics which are not part of the generator. Signals are sent down this cable toset the operating parameters of the generator and to read t
