Abstract
A high-frequency isolated bidirectional three-level DC–DC converter is proposed for high-voltage applications. Direct current slew rate (DCSR) control of leakage inductance is proposed to minimize conduction loss and current stress in facing the load variation, the mismatch of turns ratio and circuit parasitic parameters. The mode analysis and the disadvantages of conventional PWM plus phase shift (PPS) control are addressed while these disadvantages can be dealt with the proposed control. Comprehensive comparison between conventional PPS control and the proposed DCSR control are made within the designed low-voltage side (LVS) voltage range. Besides, the implementation of the proposed DCSR control is also given. With the proposed DCSR control, lower conduction loss, lower peak current, lower voltage spike over switches can be obtained in spite of the turns ratio mismatch, load variation, and system parasitic parameters. Zero-voltage switching (ZVS) can be achieved for all power switches in spite of the power flow direction. The effectiveness of the proposed DCSR control on the proposed topology is verified by simulation and experimental results.
