Abstract:

Providing the required load’s power using Switch Mode Power Supplies (SMPS), leads to smaller and more efficient converters. Correct operation of a SMPS needs some form of control. Applying the well-known controller design techniques like root locus and Bode needs a dynamical model for system under control. Power electronics converters are dynamical variable structure systems. Extraction of small signal dynamical equations by hand is cumbersome, time consuming and error prone. Development a software to automate the small signal model extraction process of power electronics converters is the aim of this paper. Parameter’s change and uncertainty’s effects on overall system performance can be studied easily using this software. Multi graph property of developed software, allow drawing results of different simulations on the same graph. This makes comparison possible. Available commercial softwares cannot calculate the algebraic transfer functions while developed software can do this job. Contact correspondence author to receive the software.
