Abstract: This paper presents a bidirectional Four-Switch Buck-Boost (FSBB) converter with a high-voltage (HV) gate driver for use in power bank applications. The proposed FSBB is also integrated into ...

Abstract: The four-switch buck-boost (FSBB) converter has the functions of voltage step-up and step-down as well as positive output, which is suitable for the applications with wide input voltage ...

[Julian Ilett] recently posted two videos that fit this description. He built a buck converter and made measurements about its efficiency using different configurations. The test setup is simple.
