The reduction in radiated electromagnetic field of printed circuit board with active components and varying Power Distribution Networks (PDN) has been investigated. The PDN consisted of alternative power solutions such as power traces, 2 single cell Electromagnetic Band Gap structures (EBG) or asymmetric EBG. The radiated electromagnetic field of these boards was measured in a reverberation chamber...
Weak power supply networks are very sensitive to non-linear low power loads. Electronics in low power loads are non-linear, very basic, and consisting of a rectifier bridge and bulk capacitor, consuming current only in the peak of the supplied voltage. Due to the relative high power supply network impedance the waveform of the supplied voltage is heavily distorted. In this paper the effect of energy...
In modern buildings virtually all electric loads are non-linear. Neither the applicable standards for supply of electrical energy nor those for consumption of electrical energy take into account the replacement of linear loads by non-linear loads. Low power equipment is exempted in standards assuming that all other (linear) loads dominate the power quality. In modern buildings there is a huge number...
