Harmonic Analysis of Flyback DC-DC Converter

This article presents a harmonic resonance analysis of the Flyback DC-DC converter. Harmonic resonance analysis of DC-DC converters is a process that considers specific conditions where the harmonic components generated by the converters can interact with the reactive elements in the system (such as inductors and capacitors), leading to the phenomenon of resonance. This type of analysis is critical because harmonic resonance can significantly increase the voltage and/or current at certain points in the system, which can lead to component failure or system instability. A mathematical model was implemented in MATLAB/Simulink, with the help of which simulation results are presented when a disturbance unit is injected into each node of the studied power scheme.
