CPI Pulsed Power Supply EIK

Model VPW3493 is a power supply modulator (PSM) intended to operate a wide range of CPI pulsed Extended Interaction Klystrons (EIK) in a variety of applications. It is an integral AC powered unit, configured using a floating deck modulator and filament supply coupled to a synchronously switched high voltage power supply.
The power supply is designed to provide high stability for improved EIK performance with low stored energy to protect the EIK should faults occur.
An optional Control and Monitoring Unit (CMU), VZW3556, provides modulation control and monitoring for the PSM. Synchronizing and triggering signals are generated within the con-
trol unit which also serves to monitor, protect and report on the status of the transmitter. The CMU functionality could be provided by the user’s system.

The PSM performs the following mechanical and electrical functions:
- Provides suitably regulated cathode-to-body, collector-to-body (or cathode), cathode heater, focus electrode bias and focusing voltages
- Provides coherent high voltage power supply switching and EIK focus electrode pulsing
- Monitors voltages, currents and temperatures for fault conditions and performs suitable trip functions
- Mechanical configuration provides robust mounting, suitable PSM cooling and personnel safety from high voltages and hot surfaces
The optional Control and Monitoring Unit, used for operational monitoring when not supplied by the radar control system, is housed in a standard 19 inch aluminum chassis. It includes an internal preset pulse generator.
