Tiivistelmä

This paper will study the input dynamics of a buck type converter with input filter using voltage-mode and current-mode control at continuous inductor-current-mode. The relevant transfer functions are derived first without input filter and the effect of input filter is added by means of circuit theoretical manipulations. The transfer functions are analyzed in frequency domain. The effect of switching frequency as well as the propagation of rapidly varying load current pulses will be studied using MatlabTM. It is evident that the dynamic behavior of Telecom load system in the respect of EMC and the required dynamics of the down-stream converter can cause severe problems, if the input filtering and controller design is not carefully considered.
