Influence of high magnitude electromagnetic fields on on-board DC/DC-modules: practical results of testing the modules for telecom applications in GTEM-cell

摘要

Due to the rapid development of communications networks, as for instance mobile telephony, voice/data and Internet, reliable and disturbance-free data processing and transmission are becoming increasingly important. In a mobile telecom system a large number of disturbances can be attributed to radiated electromagnetic emissions from various equipment. The paper describes the OTEM-cell designed at the Faculty of Electrical Engineering and Computing in Zagreb that can be used for EMC measurements from 0.1 to 1 GHz. This cell was used in testing the immunity of the on-board power supply to the radiated electromagnetic emission. Finally, the paper presents the experimental data on high magnitude electromagnetic field impact on different on-board DC/DC modules.
