A dynamic model of a DCM boost converter is extracted using system identification techniques. The obtained model is based on the well-known frequency response method. This procedure can be used for other types of converters operating in DCM.
Improvements in power transformers will address the needs of the smart grid. Benefits include enhanced energy security, reduced greenhouse gas emissions, improved urban air quality, and greater grid utilization.
Accurate modeling of power electronic converters, i.e., obtaining control to output transfer function, must include series resistance of capacitors and inductors. A simple method allows measurement of a capacitor’s Equivalent Series Resistance (ESR).
