A Two-Phase Sixth-Order Boots Converter with Small Passive Components

A two-phase sixth order (2P6O) non-isolated boost converter is introduced in this article with an improved operation and an innovative design that considers an interleaved switching strategy for the transistors. The result is that this 2P6O converter achieves outstanding performance. In this article, the 2P6O converter is compared against the well-known and very competitive traditional interleaved boost converter for a design exercise with similar performance and equivalent switching ripples. The 2P6O contains more passive components, but the design showed that those passive components are smaller in terms of stored energy. The introduction of the additional inductor and capacitor in the 2P6O converter was compensated by the fact that all energy-stored elements became smaller. This advancement can provide more compact, efficient, and economical solutions in various power electronics applications. Experimental results are provided to demonstrate the principle of the proposition.
