Behavior of a Filter for Elimination of the 5th Harmony Caused by Components LED and Compact Lighting Lamps

The current problem in the use of lighting equipment with electronic components with low electronic compability, causes the introduction of electromagnetic disturbances to electrical equipment and systems. In addition, any electrical equipment, is a generator of electromagnetic disturbances. These cause undesirable phenomena mitigation is necessary because they are more intense with increasing voltage and current values, circuits with electronic components become increasingly sensitive and the distance between sensitive and disturbing circuits is reduced. The new technologies of LED lighting have advantages of energy saving, do not release toxic gases, do not contain harmful substances, have less energy losses and are controlled by intelligent systems. In this research, a second-order low-pass filter for the elimination of the fifth harmonic, generated by new generation lighting lamps (LED lamps and compact fluorescent lamps). A silicon controlled diode is introduced to prevent frequency rebound, allowing to have a satisfactory functioning capacity. Modeling with Matlabs Simulink is performed to obtain voltage and current waves before and after inserting the proposed filter.
