Nowadays, the presence of voltage distortion due to conducted disturbances coming from electronic converters is creating some problems, including damage to industrial or domestic equipment or control failure of the devices among other troubles. An important point to consider is the insufficient regulation of disturbances in the range from 2 kHz to 150 kHz, since present Electromagnetic Compatibility (EMC) standards cover the typical disturbances produced by loads with rectifiers. Disturbances

On the other hand, filters used in some equipment are not designed for the characteristics of the grid to which they are connected nor are standardized. And, as a consequence, conducted disturbances are transmitted through the grid, creating problems in different points. This problem will be analysed in three different cases: industrial converters, wind plants and Low Voltage (LV) photovoltaic generators.
