Abstract

This paper dedicated to study indirect control of Cuk converter. Cuk converter has a 4th order non minimum phase transfer function. Extraction of converter's dynamical equation is not an easy task with pencil-and-paper analysis. Converter's dynamical equations are obtained using "Kocaeli university's converter dynamics toolbox for MATLAB (R)" developed in Kocaeli university's power electronics research group. Presence of Right Half Plane (RHP) zeros force us to use two feedback loops. Controllers are designed for this two loops using MATLAB's control system toolbox. Close loop system is tested in Simulink (R) environment. Simulation results showed the performance of designed controller.(C) 2017 The Authors. Published by IASE.
