What is a Multiplier?

Voltage multipliers are AC-to-DC power conversion devices typically comprised of diodes and capacitors.  Voltage multipliers produce a high potential DC voltage from a lower voltage AC source.

Common Multiplier Applications
Originally used for television CRT's, voltage multipliers are used in laser systems, x-ray systems, traveling wave tubes, ion pumps, electrostatic systems, copy machines, scientific instrumentation, oscilloscopes, and many other applications that utilize high voltage DC.
