MATLAB/Simulink-Based Linearization Model of a Boost DC-DC Converter

In this paperwork is presented MATLAB/Simulink base approach for model linearization of power electronic devices. Analyzed problem is important for optimal design, control loop synthesis, stability analysis and guaranteeing the parameters of power electronic devices and systems. The process is described in details step by step with example of Boost DC/DC converter. The linearization results are verified by comparison with laboratory sample and in addition Bode-Diagrams of model and mock-up are presented. Proposed approach is useful to be applied in the field of research and development and power electronics education classes, because it is suitable for automation and doesn’t require users to have in-deep knowledge of mathematics and control systems. The application of mathematical software enables students with less fundamental training to solve practical problems related to optimal design and synthesis of management.
