Conducted emission variations using low power LED lamps connected to other devices
In this paper, an analysis of the emissions of an LED lamp is performed, when it is connected in parallel with electrical devices of linear and non-linear behavior. The objective is to determine if the presence of other loads connected in the same installation can cause a change in the emissions of the LED lamp. A measurement assembly and a test electrical network are built to perform the measurements of voltage and current emissions generated by the LED lamp between 1 Hz and 250 kHz. Incandescent, CFL and LED lamps of different power and technology are used as test loads. The analysis of results indicates that the increase of devices connected in parallel to an LED bulb can in general reduce the current THD. However, there are components in the current emission that increase their RMS value.
