High switching frequencies(>1 MHz) become available due to the development of wide bandgap semiconductors. This trend of increasing operating frequency in power electronics results in the reduction of output filter sizes and costs. As frequency increases, parasitic behavior of components become more dominant. This paper shows the possibility to shift the generated EMI peaks to the most effective...
Modern so-called energy efficient equipment often draw current only during a very short period of the period of a power supply mains. This is causing unwanted non-sinusoidal and harmonic currents. In some cases even a single diode is used for rectification causing direct current (DC) in the mains supply. To reduce dissipation the semiconductor components switch very fast, which is causing interference,...
