Course content

Signification of electromagnetic compatibility (EMC) for the operation of electrical and electronic devices, definition of EMC as well as basic expressions (electromagnetic interference, electromagnetic immunity to a disturbance etc.), Examples of the EMC ignorance and its consequences, EMC legislature, impact of electromagnetic fields on live organisms. Interference sources (industrial ones, natural ones), reasons of the overvoltage rise. Interference types (noise, impulsive disturbance, continuous disturbance, quasi impulsive disturbance). Disturbance signal transmission to the affected object (electromagnetic wave propagation in space, signal propagation along a line, attenuation and phase determination, various types of coupling). Protection limiting the interferences (suppressor capacitors, suppression chokes, filters, electromagnetic shielding). Protection against the overvoltage (arrester spark gap, lightning arrester, varistors, Zener diodes, suppressor diodes, fuses. Measurement for electromagnetic compatibility (antennas for measurement, EMC chamber, free space measuring site, devices for interference measurement.
