In this paper, an overview of three different DC-DC boost converters - Diode Rectification boost (DR),Synchronous Rectification boost (SR) and Interleaved boost (IL) - is carried out. The goal is to compare theenergetic, thermal and reliability performances of the converters under investigation ...

For the selected topology, the synchronous variable speed turbines are connected in parallel to a DC-BUS without using DC/DC converters. Thus, all of them generate on average the same voltage, even if they face different river speeds. Special considerations were taken to find the maximum power...
Usually, unidirectional chargers employ a diode bridge, a filter, and DC-DC converters. A generic layout of these chargers is presented in Figure 2.12. Bidirectional chargers, in contrast, enable the vehicle to inject power back to the grid, which allows the PEVs to act as mobile storage ...
