Power characteristics analysis of bidirectional full-bridge DC-DC converter with triple-phase-shift control

This paper analyzes the control performances of the triple-phase-shift (TPS) control and the operating mode of bidirectional full-bridge DC-DC converter under this control. Then the corresponding mathematical model of the converter is established and the related power characteristics are also analyzed. Moreover, the related formulas of the converter under TPS are derived for the convenience of comparative analysis between TPS control mode and dual-phase-shift (DPS) control mode. Then the paper points out that triple-phase-shift control not only retains the advantages of dual-phase-shift control, but also shows some other obvious advantages such as a small peak current and RMS current, low reactive power, and high efficiency, etc. At last, simulation base on matlab/simulink verify the excellent performance of the triple-phase-shift control.
