Mathematical Modeling and Dynamic Analysis of Self-Lift P/O Lou Converter by Means of Signal Flow Graph

Modeling of dc-dc power converters is of great importance to obtain frequency response. Modeling is first step to design compensator circuits for a closed loop system. Computer devices were only able to find dc operating point and to produce diagram boot for circuits with linear elements. Power converters involve diodes and switches and since these elements are non-linear, it is impossible to access dc operating point and diagram boot in such converters. This is while temporal responses can also be simulated. In this article we used current signal graph and Maison operation formula to obtain small signaling model, output control transfer functions (switching), output to input and diagram boot of Luo self boosting converter. Results obtained from simulations in MATLAB software were presented to investigate sustainability and also frequency response.
