Abstract. The effectiveness of the use of computer equipment highly depends on its proper functioning under the influence of external factors, including noise immunity when electromagnetic interference takes place. The origin of violations of the noise immunity of computer equipment is often the effect of electromagnetic interference from power supply network. An effective solution of the problem of noise immunity of the computer equipment is taking it into accounting at the design stage. A decision about the necessity to improve the noise immunity of computer equipment under the influence of electromagnetic interference is formed on the base of the forecast results. In this paper we propose a methodology and mathematical models to predict the noise immunity of computer equipment under the influence of electromagnetic interference from power supply network. The example of the prediction is presented. The results of experimental studies of noise immunity of computer equipment under the influence of electromagnetic interference from power supply network are presented. Technical solutions aiming at the improving the noise immunity of computer equipment under the influence of electromagnetic interference from power supply network are considered. The results of research on the effectiveness of technical solutions are presented.

Keywords: computer equipment, electromagnetic interference, power supply network, electromagnetic compatibility, noise immunity, modeling, experiments.
