Design of isolated class-Φ2 DC-DC converter based on harmonic analysis technology

This study proposes a design method for an isolated class
$-\Phi_{2}$
DC-DC converter. By using the proposed design method, it is possible to design an isolated class
$-\Phi_{2}$
DC-DC converter with an arbitrary switch on-duty ratio
$(D_{\mathrm{s}})$
. The proposed design method can be implemented without a considerable amount of tuning and the converter satisfies the zero-voltage-switching and zero-derivative-switching (ZVS/ZDS) conditions. In this study, an isolated class
$-\Phi_{2}$
DC-DC converter is designed and fabricated using the proposed design method and an analysis of its performance was conducted. The results of the analysis, Simulation Program with Integrated Circuit Emphasis (SPICE), and the experiment are compared.
