Abstract: The use of a digital architecture in PWM controllers for Point of Load applications, together with system identification techniques, allows the development of fully automated routines for in-situ system performance optimization where controller parameters are specifically tailored to the application. In this context this paper proposes a method to perform parametric system identification of digitally controlled power converters using a conventional analog Frequency Response Analyser (FRA). Non-linearities intrinsic to the digital loop are taken into account thus leading to accurate estimation of converter parameters. The proposed method has been verified on a digitally controlled POL Vin=12V, Vout=1.2V, Iout=10A, Fsw=400kHz for various bulk capacitor scenarios.
