A NOVEL METHOD TO ACHIEVE ZERO-VOLTAGE REGULATION IN BUCK CONVERTER

The Function Control law for Buck converter is derived to achieve zero voltage regulation of the output voltage, A new method to retrieve th e low frequency component of the inductor voltage is proposed and anal yzed, The stability of the closed loop system using proportional and d ifferential controller is analyzed, The effect of the supply voltage a nd load current disturbance is also studied, The analysis, computer si mulation by PSPICE and experimental results illustrate that excellent performance can be achieved by the Function Control law.
