A Soft-Switching Control for Cascaded Buck-Boost Converters Without Zero-Crossing Detection

IEEE Access, 2019
This paper proposes a novel soft-switching control without zero-crossing detection for the cascaded buck-boost converters (CBBCs). The proposed soft-switching control consists of two parts: soft-switching modulation and closed-loop control.
