Soft-Switched Three-Port DC-DC Converter With Simple Auxiliary Circuit

IEEE Access, 2021
In this paper, a new high efficiency soft-switching non-isolated three-port converter (TPC) is proposed. In the conventional TPC, three switches are required to process power in different directions between inputs and output.

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.
