4.7 Front Panel Assembly

Front Panel control meters, and status indications are
connected to the FRONT PANEL PWB. The FRONT
PANEL PWB interfaces directly to the
CONTROL/POWER PWB.

4.8 Filament Supply PWB

The power for the X-ray tube is provided by the filament
inverter. The filament inverter is a high frequency, series
resonant inverter. The inverter provides regulated current
to the primary of the filament transformer. The filament
isolation transformer output is then rectified by CR8 and
CR9, filtered by C6 through C11, and then connected to
the output block terminal TB1.
