In this webinar we demonstrate how common-mode chokes, which represent an essential component for filtering of common-mode noise in electronics, can be used in the simulation tools QUCS and LTspice®. By means of LTspice® it is illustrated how measured scattering parameters of those components are embedded into existing circuits. The results are compared to the models from the standard library which are based on an equivalent circuit. It also shows how 4-port simulations can be carried out under LT-Spice with the aid of a special circuit. With the help of a template for the simulation tool QUCS it is shown how various parameters of common-mode chokes can be derived from the scattering parameters.
