要約(英語): The multi-phase method is effective in downsizing the power converter system. Because of the multi-phase boost chopper circuit, the output capacitor and the cooling system can be downsized in the case of the boost chopper circuit. Furthermore, the volume of the inductor can be reduced using the transformer-linked method. However, there is little comparative data available on the output capacitor in the boost chopper of the conventional multi-phase method and the transformer-linked method. The purpose of my work was to examine the characteristics of the output capacitor in both the multi-phase method and the transformer-linked method. To evaluate the performance of the downsized capacitor, a voltage ripple analysis has been successfully employed as the index of the volume of the output capacitor. From the experimental results, it was found that there is little difference between the multi-phase method and the transformer-linked method in regard to the voltage ripple of the output capacitor. The experimental results indicate that the performance of the downsized capacitor is the same for the multi-phase method and the transformer-linked method.
