Simulations to Eliminate Backflow Power in an Isolated Three-Port Bidirectional DC–DC Converter
Energies, 2022 The aim of this work was to eliminate the backflow power present in an isolated three-port DC–DC converter. Backflow power (which is an inherent property of phase-shifted DC–DC converters) is the major contributor of circulating current the converter ...
