Abstract
This paper discusses the measurement of frequency response functions at the input and output terminals of a prototype dc-dc buck converter. The frequency domain identification procedure is applied to the measured frequency response functions. The set of these transfer functions is used for black-box modeling of dc-dc converter. Distributed power systems are comprised of numerous such converters in various configurations. The system level analysis of such systems becomes complex when individual converter models are of high order. So a model order reduction technique is applied to reduce the order of the transfer functions. While reducing the order of the system, it has been ensured that the system retains the dynamics of the full order system.
