Mathematical Modeling of Non-ideal Zeta Converter Using Tags in MATLAB/Simulink

Abstract

 -There are various computer-aided software available to simulate dc-dc power converters using discrete semiconductor devices. Specifically, MATLAB is widely popular for simulation of power electronics converters. For these simulations, MATLAB provides a dedicated toolbox namely 'SimPowerSystem'. However, this paper presents an alternative approach to simulate power electronic circuits without having this toolbox. This approach is explained with example of a fourth-order non-ideal dc-dc Zeta converter. This method avoids the use of discrete semiconductor devices, resulting in fast and efficient simulation model. The effect of non-idealities of Zeta converter is also included in the simulated model. The simulation results verify that the different voltage and current responses are exactly same as obtained with 'SimPowerSystem' toolbox.
