LOW NOISE DC POWER SUPPLIES

Vaclav Papez, Stanislava Papezova

Abstract

Some measuring systems are very sensitive on disturbances incoming from power supplies. If no accumulators are used for their power supply, which ensure a minimum signal noise and transmission jamming signal from power network, special power supplies have to be constructed for them. An example of a possible influence of a disturbance, which spreads along to the power supply on high pure sine-wave signal source, is presented in our contribution, whereas the requirements on the power supply are also specified. Furthermore, an analysis of the construction of these sources is effected and a sample of the source construction and records are introduced.
