摘要

In this research, the output voltage characteristics of two DC power sources are compared. Both nickel-cadmium DC-DC buck converter and direct ethanol fuel cell DC-DC buck converter systems are experimentally evaluated over a selected switching frequency range. The output voltage characteristics of two types of direct ethanol fuel cell DC-DC buck converter systems are determined. Experimental results are compared to simulations of Fourier-series models of each DC system. The output voltage obtained through simulation and the theoretical output voltage of each system are identical.
