Transformer Assembly T1
The Transformer Assembly consists of a HV Transformer primary winding and secondary
winding which is then connected to HV Assembly by HV connectors. The HV Transformer
leakage inductance together with the combined capacitance of the transformer secondary,
and the HV Section, produces a resonant tank on the primary side of transformer. This
resonant frequency is close to the HV Inverter switching frequency, provides for soft
switching thus reducing heat dissipation and EMI. The HV Transformer T1 steps-up the
drive from the Power Inverter Assembly to the level sufficient for producing a desired DC
High Voltage by the HV Multiplier Assembly located in the HV Assembly Section.

HV Assembly
6.6.1.
HV Multiplier Assembly
The HV Section contains HV Multiplier Assembly, Current Limiting Assembly, HV
Divider and HV Output Cablewell J1. All these components are encapsulated in silicon
rubber. The Current Limiting Resistors limit the X-Ray Tube arcing current. The HV
Divider provides a HV Feedback Signal for the feedback. The HV multiplier assembly is
connected to the terminals of the Cablewell J1. The HV Cablewell J1 is a 3 socket type
HV receptacle.

Filament Rectifier /Transformer Assembly
Filament Transformer T1, T2 supplies voltage to the Dual Filament Rectifier. Dual
Filament Rectifier rectifies and filters the voltage with LC type filter. This DC voltage
supplies the appropriate filament, large or small on the J1 socket.
