Abstract. Computers are widely used
in everyday life. The effectiveness of their use is closely related to reliable
operation in actual operating conditions, where there are various sources of
electromagnetic interference, including static electricity. Maximum values of
the potential up to which a human body can be charged are up to fifteen
kilovolts. The quality of the functioning of computing when exposed to
electrostatic discharges on the metal case of the device and the ground circuit
are paper discusses. The levels of noise immunity of modern computers to the
effects of single electrostatic discharges are identified. The results of
studies of electromagnetic interference in computers when exposed to
electrostatic discharge are presents. The maximum magnitude of electromagnetic
interference significantly depends on the voltage of the electrostatic
discharge, the area of the structural holes and can reach several volts.
Mathematical models for modeling the current of electrostatic discharge are
proposed. The methods for improving the noise immunity of computers under the
influence of electrostatic discharge are considered.
Key
words:
computers, electrostatic discharge, noise immunity, electromagnetic
interference, experimental research, simulation, interference reduction.
