Power electronics´ polluting effects

In use far and wide for improved delivery and control of the electricity supply, power electronics systems are both the cause and remedy of the power system harmonic pollution problem. Here, the authors describe how an insidious side-effect of any solution involving power electronics converters is their generation of high-frequency pollution-namely, conducted and radiated noise in the 100 kHz to 100 MHz range-which can have an adverse effect on the operation of surrounding electronic equipment. Solutions to this problem are also offered in this paper
