3-winding flyback transformer model extraction\ud using time domain system identification

摘要

For low frequency applications, transformer\udmodel extraction has been widely investigated using both\udtime and frequency domain data. However, the studies for\udhigh frequency transformers have been carried out in the\udfrequency domain only. The reason is due to the complications\udin acquiring time domain data for high frequency transformer\udmodel estimation. This paper presents a methodology to deal\udwith the numerical difficulties associated with time domain\uddata collection, and to obtain a frequency-dependent model\udof a 3-winding flyback transformer using time domain system\udidentification techniques. The obtained transformer model is\udexperimentally verified.
