A New Circuit Design of Two-Switch Buck-Boost Converter

A conventional two-switch buck-boost (TSBB) converter can operate in buck, boost, and buck-boost modes. This paper introduces a new topology for a two-switch buck-boost converter with the same operation modes. However, the proposed TSBB converter has fewer conductions and switching components than t...

Summary:A conventional two-switch buck-boost (TSBB) converter can operate in buck, boost, and buck-boost modes. This paper introduces a new topology for a two-switch buck-boost converter with the same operation modes. However, the proposed TSBB converter has fewer conductions and switching components than the conventional TSBB converter, which reduces the power losses.
