Harmonic Analysis of ZETA DC-DC Converter

In the present work, a harmonic resonance analysis of the ZETA DC-DC converter has been implemented. Differential equations were used to describe the principle of operation of the converter. MATLAB/Simulink software was used to simulate the circuit and simulation results were obtained in which magnitude was observed in each of the nodes of the circuit with an input disturbance of 1 p.u. current. From the obtained simulation results, an analysis with the advantages and disadvantages of the scheme is presented, and it is also possible to observe which of the nodes is most susceptible to resonance phenomena.
