• single-switch buck-boost (SSBB) converter
• two-switch buck-boost (TSBB) converter

This paper presents a new buck-boost converter. Unlike the single-switch buck-boost converter, the proposed converter has low-voltage stresses on semiconductors. Moreover, although both the conventional twoswitch buck-boost (TSBB) and the proposed converters have the same number of passive and active components, and the proposed converter can reduce the conduction loss as a result of having fewer conducting components. Therefore, the proposed converter obtained a higher efficiency than the TSBB converter. A 48-V output voltage and 150-W output power prototype was fabricated to verify the effectiveness of the proposed converter.
