Non-intrusive parameter estimation method for autotuned DC–DC converter based on quasi-impulse response

A non-intrusive method to estimate the values of power-stage components online and autotuning of feedback compensator for digitally controlled power converters is presented in this study. By using buck converter as an example, the presented autotuning controller has been designed to cover the wide-range variations in equivalent series resistance zero of the output capacitor and the resonant freque...
