The PVX-2110 high power pulse generator (pulsed volt­age source) is designed for pulsing low impedance loads
(from 1Ω to 25Ω) at up to 200V and 50A, with pulse widths
from 200ns to 2ms

. The exceptional pulse fidelity of the

PVX-2110 will optimize the performance of any system in
which it is used.

The PVX-2110 can deliver up to 10kW of peak output
power and 5kW of average output power, making it well
suited for use in materials testing and processing, semi­conductor testing and characterization, and other test and
measurement and R&D applications.

The PVX-2110 requires a TTL gate signal and high volt­age DC power supply inputs. The output pulse width and
frequency are controlled by the gate signal. The pulse out­put voltage is controlled by the amplitude of the input DC
power supply.

The PVX-2110 features front panel indicator LEDs to
monitor the status of the pulse generator. Front panel volt­age and current monitors provide a straightforward means
to view the output voltage and current waveforms in real­time, eliminating the need for an external high voltage os­cilloscope probe.

The output cable supplied with the unit is an inn ovati v e
custom designed multi-coaxial cable with an impedance of

5Ω. The design of this cable maintains the fidelity of the
output pulse without introducing pulse distortion or ringing,
and provides a convenient means of connecting the pulse
generator to the load.

The PVX-2110 has over-current detection and shut-down
circuitry to protect the pulse generator from potential dam­age due to over-current conditions such as arcs and shorts
in the load or interconnect cable. If an over-current condi­tion is detected, the output pulse is truncated for 10 milli­seconds. The pulse generator then automatically re­enables the output, and will continue pulsing, unless the
over-current condition persists. It is also protected against
operation at excessive pulse widths or frequencies.

The pulse generator is a direct-coupled, air-cooled solid­state design, offering fast pulse rise and fall times, low
power dissipation, and virtually no over-shoot, under-shoot
or ringing. All control and protection logic circuitry, support
power, energy storage and output network are incorporated
into the PVX-2110. It is connected directly to the load, and
does not require series or shunt resistors, impedance­matching networks between the pulse generator and the
load, or additional energy storage (capacitor banks). All of
this is taken care of within the PVX-2110.

(1) When driving loads with impedances <5Ω, the output voltage must be limited to <200V,

so that the peak output current (V/R) does not exceed 50A, and the maximum average

current (defined as I x Duty Cycle) does not exceed 25A.
(2) Peak output power is defined as V x I during the output pulse.
(3) Average output power is defined as V x I x Duty Cycle.
(4) Input DC power supply must be the same polarity as the PVX-2110 (i.e. a positive output

PVX-2110 requires a positive high voltage DC input).
