The high frequency voltage oscillation on the DC/DC gate driver of a H-bridge created during the turn-off intervals of the power switches has critical impact on component reliability and control quality. This noise can propagate freely in the low power plane to other functional circuits of the converter due to the performance degradation of EMI filter in high frequency range above 30MHz. In this paper,...
The impedance modeling of passive device is mandatory for EMI prediction of power converter on printed board circuit (PCB) level. The black-box node-to-node impedance function (NIF) model, which extracts the connecting impedance matrix from measurement, can be used as the most general representation. However, the most recent development of this model is still based on the assumption of ideal shorting...
