Isolated DC-DC Converter Structure Selection to Provide Minimum Power Losses in Active Components
The results of static power losses estimation in switching elements and diodes of isolated DC/DC converters are examined using Buck and Boost topologies with single-stage and two-stage structures. Comparison of relative power losses in power switches and diodes of four equivalent structures of converters in the range of supply voltage is carried out. The most effective structures at different of supply voltage ratios are determined.
