This paper analyzes the source of Electron-multiplier voltage suddenly disappearing without direct cause and lon-gauge unnormally lighting, and proposes a method handling above troubles.

A powder gun that has a low voltage single supply to it, and steps up the current to high voltage via a cascade multiplier located in the gun barrel.

In this paper, we studied on critical current mode active Power Factor Correction technology, and did a detailed analysis and design on voltage reference circuit and analog multiplier circuit.
