BELUSSI, C. H; GOMEZ BERISSO, M  and  FASANO, Y. Low-noise High-voltage DC Power Supply for Nanopositioning Applications. An. AFA [online]. 2015, vol.26, n.4, pp.162-166. ISSN 0327-358X.

Nanopositioning techniques currently applied to characterize physical properties of materials interesting for applications at the microscopic scale rely on high-voltage electronic control circuits that should have the lowest possible noise level. Here we introduce a simple, flexible, and custom-built power supply circuit that can provide +375V with a noise level below 10 ppm. The flexibility of the circuit comes from its topology based on discrete MOSFET components that can be suitable replaced in order to change the polarity as well as the output voltage and current.

Keywords : High-voltage; Low-noise; Power-supply.
