EN This paper presents the concept of using a two-stage power supply unit to reduce the harmonic frequencies of electric current generated by light-emitting diodes fitted with an integrated power supply and driver. In the work, there are references to the most important Standards pertaining to generation higher harmonics of current. It also provides information on the experimental setup and the measurement methodology. Subsequently, the paper discusses and analyses the research results. Finally, there are conclusions and observations on the conducted study.
