Abstract
An experimental research of power LED driver ITSK-17507conductive emission interference is considered according to the requirements of EN 55015:2006 «Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment». According to the requirements of EN 55015:2006 the technical specifications are described.The conductive interference emission measurements results of power LED emitters driver ITSK-17507 allow to obtain amplitude changing diagram in the frequency range 0.009-30 MHz. In the frequency range 0.15-1.5 MHz the exceeding of EN 55015:2006 requirements is 10-15 dB. Identification this problem at the design stage allows to prevent this exceeding without additional financial and time outlay, which are required in accredited electromagnetic emission laboratories. The power LED driver research analysis with the improvements provides full compliance with the EMC requirements.
