Backflow Power Optimization Control for Dual Active Bridge DC-DC Converters [PDF]
Energies, 2017 This paper proposes optimized control methods for global minimum backflow power based on a triple-phase-shift (TPS) control strategy. Three global optimized methods are derived to minimize the backflow power on the primary side, on the secondary side and

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 ...
