Performance of a Zero Average Dynamics-controlled buck converter using different pulse-width modulation schemes

Abstract

The response of a digital Zero Average Dynamics (ZAD)-controlled buck converter under the variation of its intrinsic parameters as well as the pulse-width modulation signal is studied in detail. The multiparameter analysis presented here leads to a complete knowledge of the different dynamical scenarios exhibited by the system. Numerical results indicate that the success of the ZAD-strategy is highly dependent on the parameter and pulse-width modulation (PWM) combinations. Experiments are included to validate the performance inside the so-called optimum region.
