The formulas above assume ideal components, but real-world devices have additional elements that turn them into L-C-R combinations (a primary attribute plus two parasitic elements). These parasitic elements change the real component behavior compared to the ideal version and affect the filter perform...
Taking into account the following hypothesis: Rt > Rd, Rg > R and Rload > Rd, gives these formulas:: Vinput = Rg.VBR + Rd. Vg Rg Voutput = Rt.VBR + Rd. Vinput Rt The results of the calculation done for VPP = 8 kV, Rg = 330 W...

By taking into account these following hypothesis : Rt>Rd, Rg>Rd and Rload>Rd, it gives these formulas: Vinput = Rg.VBR + Rd.Vg Rg Voutput = Rt.VBR + Rd.Vinput Rt The results of the calculation done for Vg=8kV, Rg=330Ω (IEC61000-4-2 standard), VBR=7V (typ.) and Rd...
, a disadvantage of the conventional technologies is that the output of the power supply will carry an unexpected ripple signal when there is frequency hopping. How the unexpected ripple signal is generated in the presence of frequency hopping will be described below with reference to the formulas...
This is, in fact, the way in which formulas analogous to the EMI model were proposed in [23]. Suppose we conjecture twist operators with the form of coherent operators τA(n) = ei A dx α(An)(x) φ(n)(x) , (7.1) where φ(n)(x) is some generic Gaussian field (free or ...
