AN-0100 - Using a VMI Opto-coupler in Conjunction with High Voltage Relays

From Voltage Multipliers, Inc.

This application is for use in a scanning electron microscope, which has different operating
modes. In one mode, a large negative voltage (nominally -10kV) must be applied to an
electrode. In the other mode, a small voltage must be applied, but with a high current
capability. In both cases, the voltage must be very precise and low-noise. But the concept
can be applied to any configuration where a relay is used to switch between sources that
involve high voltage.
