Design

The PVM-4150 is a compact, OEM-style pulse generator

module producing fast, high voltage wave forms to

1,500V. Optimized for driving high impedance capacitive

loads, the PVM-4150 is well suited for driving extraction

grids and deflection plates for electrostatic modulation of

particle beams in time-of-flight mass spectrometers and

accelerators. Its robust and versatile design also makes it

well suited for pulsing or gating power tube grids, Pockels

cells and Q Switches, acoustic transducers, microchannel

plates, photomultiplier tubes and image intensifiers. The

exceptional pulse fidelity of the PVM-4150 will optimize the

performance of any system in which it is used.

The PVM-4150 will generate an output voltage pulse of

1500 volts with rise and fall times less than 25ns, with very

flat voltage pulses to DC into a capacitive load. It can gen-

erate singled-ended output pulses from ground to +1500V

or from ground to -1500V, and can also generate pulses

originating from a DC voltage offset from ground by using

both VLow and VHigh power supply inputs.

The PVM-4150 requires user-supplied +24VDC to

+28VDC support power, a TTL gate signal, a high voltage

DC power supply and optional DC offset 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 supplies.

Unlike some competing solid state switches, the PVM-4150 in-

corporates all control and protection logic circuitry, energy stor-

age and output network. It can be connected directly to the

load, and does not require series or shunt resistors, impedance-

matching networks between the pulser and the load, or addi-

tional energy storage (capacitor banks). All of this is taken care

of within the PVM-4150. The pulser is housed in an aluminum

enclosure, with threaded mounting holes in the base to simplify

installation and assembly in OEM applications.

The PVM-4150 pulser is a direct-coupled, all solid-state de-

sign using air as the primary insulating medium. Its conser-

vative design margin gives you long component life. And

keeping the PVM-4150 free of potting compound or encap-

sulation materials makes it easy to service if a component

ever does require replacement. Some competing products

are potted, and must be replaced if they fail. But compact-

ness and durability are not all you get in the PVM-4150. In-

herent in the design is exceptional pulse fidelity with virtu-

ally no ringing, over-shoot or under-shoot, high average

power handling capability, and protection against arcs,

shorts and load transients in a reliable, economical module.

The pulser is a half-bridge (totem pole) design, offering

equally fast pulse rise and fall times, low power dissipa-

tion, and virtually no over-shoot, under-shoot or ringing.

The PVM-4150 has over-current detection and shut-down

circuitry to protect the pulse generator from potential dam-

age due to arcs and shorts in the load or interconnect ca-

ble.
