OVERVIEW<br />

KV GENERATION<br />

kV is regulated by a dynamic, self correcting servo control loop <strong>com</strong>prised of a duty<br />

cycle controlled high voltage drive circuit, drive PAL, control amplifier, error amplifier and<br />

sense circuits<br />

In the Auto mode, the Technique Processor PCB varies the kV according to the video<br />

level signal received from the CCD camera until the proper level is achieved.<br />

In the <strong>Manual</strong> mode, the operator varies the kV<br />

Power for X-ray generation is buffered by battery packs. This allows the generator to run<br />

on standard single phase AC power.<br />
