Abstract

Many problems that of appear coming from power supply noise, many methods to reduction noise using traditional component like capacitor. The capacitors are used to smooth as filter the pulsating DC output after rectification so that a nearly constant DC voltage is supplied to the load. The voltage is measured from the terminals of the power supply from distributed control systems, the voltage coming
from variation supply are +5, 15, -15 and +24 VDC and will continue to be monitored as a guarantee that the supply voltage is in accordance with the recommended. In this paper, we will show the results of the design and implementation of the filter to monitor the ripple voltage at the output of the power supply distributed control systems in geothermal power plants.
