to minimize IGBT switching losses and to reduce EMI noise that might be produced by the 

High Power Switching power supply. The IGBT’s are mounted on the heat sink and located 

between the IGBT’s , mounted directly on the heat sink is a thermal switch that monitors the 

temperature of the inverter plate. If heat temperature exceeds 80 deg C, Over Temp Fault 

will occur.  

 

 

The inverter modules drive the HV transformer T1, which is located near the HV assembly.

Filament Inverter/Feedback (460158-XXX) 

6.4.1. 

Filament Inverter 

The Filament Inverter uses two IGBTs in a half bridge configuration to drive filament 

transformers Small or Large Filament located on the HV Assembly. The Filament 

Inverter uses the same PWM technique as the HV Inverter but in this case it’s hard 

switching. The IGBT’s are driven by the PWM located on Filament /Feedback board via 

the Gate Driver Transformer. Filament Inverter current is monitored on the primary side 

of Filament Transformers using Current Transformer and a RMS converter that is 

calibrated to provide actual filament current that is scaled 10VDC= maximum specified 

Amps.  If Filament Current fails to be regulated to the programmed Filament current, 

Filament regulation error will occur and a filament fault will be issued by the DSP. 

Filament selection L/S is monitored by a filament confirm signal to the DSP and if 

filament selected is not equivalent to confirm signal, the DSP will issue Filament Fault. 

 

6.4.2. 

kV and mA Feedback 

The Low End 460158-XXX PWB includes kV and mA Feedback Calibration circuitry and 

Arc Detector circuit. The kV and mA Feedback Signals are scaled to 10VDC each that 

represents full-scale value for nominal output voltage and current. The Filament 

Inverter/Feedback PWB receives arcs and kV and mA feedback signals from the High 

Voltage Section and sends arcs and calibrated feedback signals to the System Control 

board. ICs U1 and U2 are used for calibration of voltage and current feedback signals. 

The Arc Detector, Current Transformer T1, detects arcs in the Load or in the HV Section 

and then it’s rectified by CR2, which provides an arc pulse to the system control.
