Design, Analysis and Performance Characterization of Dual-Active-Bridge DC-DC Converter Utilizing Three-Phase Resonant Immittance Network

This paper proposes a three-phase dual-active-bridge (3p-DAB) dc-dc converter that utilizes three-phase resonant immittance network (3p-RIN) to achieve the unity power factor operation. The proposed 3p-RIN maintains the unity power factor operation at both ac links of the 3p-DAB over full range of operation; thus, mitigating the reactive power loss. It can perform the full ZVS operation as well fo...
