LOW NOISE DC POWER SUPPLIES
Václav Papež, Stanislava Papežová · 2009
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.
