14:00 Conducted EMI and Power Quality (30 Hz - 10 MHz, including the 2-150kHz 'gap')
Prof. Dr. Frank Leferink, University of Twente, De Lutte, Niederlande
The interest for conducted interference effects is changing in time. Harmonic distortion and transient issues are known and can be solved by standard solutions. The new challenge is the frequency range 2-150 kHz. In this range some people would like to use the mains supply grid for (power line tele-) communication. On the other hand, the same grid is used as a sink of interference caused by many modern product electronic devices, ranging from energy saving lighting to active infeed converters used for solar energy systems. Many interference cases have been reported on disturbance of power line telecommunication signals used for Smart meters, but PLT signals are also causing other systems to malfunction, or even damaged. The cause for interference problems is the widespread use of power electronics in all kind of equipment. Power electronics are non-linear, and are also non-stationary. At the same time the need for PLT for Smart Cities (and Smart meters) is introduced in many countries. The basic concepts and challenges will be explained in this workshop. We will discuss the optimization and use of filters, commercial of the shelf as well as novel designs. The problems due to design constraints will be explained in detail. New materials, applied in a novel way, as well as new measurement techniques will be described. Simulation and measurements results of actual designs will be used many times to explain and prove the concepts applied. Many cases will be used to substantiate solutions implemented.
