40 kHz pulses
Pulses at 40 kHz pass to the filament inverter driver, the output of which goes to the filament
transformer in the tube-head. The inverter current is sensed by a dedicated resistor.
20 kHz pulses
During preparation, pulses at 20 kHz pass to the High Voltage (HV) inverter driver. During exposure
the pulses pass also to the High Voltage regulator driver.
The output voltage of the regulator depends on the duty cycle of the driving pulses.
The output of the inverter is connected to the HV transformer in the tube-head. The inverter current is
sensed by a current transformer.
The regulation section controls the level of kV and mA by comparing the feedback signals with the
reference signals set by the control unit.
The anode voltage (kV) is determined by the input voltage to the high voltage transformer (tube-head).
The anode current (mA) is determined by the filament supply.
Calibration is required only for the filament supply.

2.1.8. Control unit
The control unit is the heart of the system.
It acquires the data set by the operator during technical parameter and program type selection, manages the output
signals and controls X-ray emission and movement of the rotating arm during exposure.
It displays alarm messages if incorrect commands are executed or in the event of malfunctions or unsafe operating
conditions.
More in detail:
• It drives the motor for rotation and translation of the rotating arm during panoramic exposure.
• It drives the cassette drive motor.
• It synchronizes the sensor reading for digital systems.
• It has an analogue input for 38V voltage control.
• It has an analogue output for PWM control of the high voltage (kV) and the filament current (for regulation of the
anode current (mA).
• It has a digital output for the radiation signals and the end-of-cooling alarm signals.
