Comparison of Single - Phase-Shift And Extended -phase -shift Modulation of Isolated Bidirectional DC-DC Converter

To ameliorate the chracterisation of isolated bidirectional Dual-Active-Bridge DC–DC (IBCD), various modulation methods are present . two control methods , single phase-shift control (SPS), extended phase shift (EPS) are research and compared for a full-bridge-based isolated bidirectional dc–dc converter , analysis of operation mode and demonstrating mathematical models of transmission power, backflow power, and current stress. finally , simulation results confirm the correct performance of EPS control.
