Abstract

Digitization of the control loop for high frequency dc-dc switching converter are increasing the application areas of modern semiconductor based power system. This paper aims at detail modeling of buck converter design considering the ESR resistances and incorporates the optimized ADC converter, DPWM and PID compensator loop to enhance and stabilized the working of high frequency DC-DC switching converter. The mathematical model of buck converter is simulated in Matlab/simulink environment to validate its performance with digitized feedback.
