Zusammenfassung: | Two-switch buck-boost (TSBB) is one of the non-isolated dc-to-dc converters that can change its mode from among buck, boost, and buck-boost modes. Changing its mode is possible by controlling gate signals. This paper presents a novel modified topology of TSBB converter. Even if the proposed converter has the same number of components as a conventional TSBB converter, the proposed converter has fewer conduction components and switching semiconductors than a conventional TSBB. This results in reduced power loss. Moreover, source terminals of metal-oxide-semiconductor field-effect transistor in the proposed converter are directly connected to ground. This configuration has an advantage in selecting gate driver integrated circuit (IC), since the IC does not necessarily need to provide high-side gate signals. A printed circuit board was designed to evaluate the improvement of the proposed converter. |
