1.4.
Capacitor Charging Technology
Capacitor charging applications require a power supply designed specifically for the task.
The 802 series supplies allow capacitors to be charged in pulse forming networks and
modulators in a very fast, efficient and controllable manner.
The units are compact high power constant current sources that can linearly and rapidly
charge a capacitive load to high voltage. Once the load capacitor is charged to the
programmed voltage, the supply will switch over to a voltage regulation mode and maintain
the load voltage at the programmed level until it is discharged.
The flexible design of the 802 allows the unit to be ordered with (L model) or without (S and
OEM model) the front panel controls and meters. Front panel controls are ideal in
applications where local control and read backs are necessary, such as R&D, laboratory
use and diagnostics. All front panel controls and indicator signals are available at the rear
panel remote control connector regardless which panel option (L, S, or OEM) is selected.
The unit is self-contained, requiring only AC power and appropriate controls. Several units
may be connected in parallel for higher power operation. There is no theoretical limit to the
number of units that may be paralleled. Typically one master unit and one or more slave or
OEM units may be used to obtain as much output power as necessary. The 802 is also
ideally suited to charge reservoir capacitors in resonant charging circuits where high rep
rates (several kilohertz) are required, such as in metal vapor lasers or solid-state
modulators.
