Comparative loss analysis of boost and synchronous boost DC-DC converters

Abstract

The following paperwork presents a comparative analysis of synchronous and non-synchronous boost converters. Analytical determination of the losses is derived and compared with the results of the simulations. The compared converters are realized and investigated experimentally. Thermographic images are used to analyze the dissipated losses in the two converters and each of their components. A methodology for magnetic components loss calculations is proposed targeting loss optimization.
