DESCRIPTION
This integrated industrial microwave power system uses a CPI
VKS-7960A klystron, designed for industrial service, as the
energy source. By using the high-efficiency, 2.45-GHz, 60 kW
CW klystron in combination with modern control and power-
supply technology, CPI is able to furnish a compact, user-
friendly, cost-effective industrial system.
The system’s control center is an embedded microprocessor
architecture which provides flexibility in selecting system
operating parameters. Operation is initiated by two independent
external enable commands. Control of the system is through a
web-based browser via a direct Ethernet or web-based
connection. Operational data is logged in the controller’s on-
board flash memory. The logged data may be uploaded to the
external computer via the Ethernet connection for use in off-
line troubleshooting or other purposes.
The high-voltage power supply consists of a phase-angle
adjustable SCR controller, a step-up transformer and a full-
wave-bridge rectifier. There is no filter capacitor on the output
of the rectifier, thus very little stored energy, which eliminates
the need for a crowbar. As such, the DC output will have a
ripple voltage of 10% p-p. This has the advantage of causing
RF output amplitude and phase variation which facilitates mode
stirring and potentially a more even heating of the process.
System interlocks will remove the high voltage in less than 10
ms in the event of a fault. In addition, the klystron beam (high
voltage) power supply is remotely located. This makes it
possible to offer the VIS-102B in a corrosion resistant sealed
stainless steel 2-bay enclosure. Cooling for the system is 100%
via water; ambient air is not used for cooling purposes. A small
flow of clean air is used to slightly pressurize the enclosure and
keep potentially corrosive local ambient air from entering the
inside of the enclosure.

Adjustable to 60 kW, maximum. Continuous control range in excess of 27 dB.
2.45 GHz nominal. Tunable over plus or minus 5 MHz
WR-430
Standard. The Klystron window and the waveguide are protected by the control system,
which will interrupt the RF drive power if arcs occur in the waveguide near the
klystron.
A directional coupler at the klystron output is included. Excessive reflected power will
also interrupt the RF drive power. A liquid-cooled, waveguide circulator capable of
dissipating the full system power is available as an option.
