| Summary: | The new simplified cascade multiphase buck DC-DC converter is proper converter for
applications with large currents, high voltage-ratio, and low ripple current. One
application example of the use of this converter is cathodic protection. In previous
research on this converter, it has been found that the most optimal converter operates
at two-cascade and four-phase. This final project is focused on analyzing the ripple on
this converter. This ripple analysis is useful for determining inductor and capacitor
filters value in converters. The consideration used in designing the filter inductor and
capacitor apart from the ripple on the inductor is also to consider the critical
inductance value so that the converter operates in a continuous conduction mode. The
ripple analysis has been carried out and the validity is verified by a series of
experiments. A comparative evaluation is also carried out on this converter with
similar converters and it is found that the proposed converter has smaller ripple on the
primary side and quite small on the output side. |
