Nonideal analysis, design and voltage mode control of a boost converter

Abstract

In this study, a practical boost converter which includes nonidealities is analysed. Nonidealities are considered such as voltage drop of capacitor equivalent resistor and inductor series resistor and diode forward voltage drop. Steady state analysis and small signal modelling is derived. Control restrictions caused by “right half plane zero in continuous conduction mode operated boost converter” is explained and a PI control technique is proposed to reduce undesired effects. Moreover, open loop and closed loop characteristics of implemented boost converter are obtained.
