The bidirectional switch-based current source converter (BDS-CSC) has broad application prospects for high-frequency bidirectional operation (rectification/inversion), which meets the requirements for reliable, efficient, and high-power-density three-phase AC-DC converter in systems such as electrified transportation and energy storage systems. High-quality operation of the BDS-CSC relies on reliable and efficient commutation and control, both of which require AC side phase voltage information. Based on this analysis, the relationship among active current vectors, the DC-link voltage and the phase voltage are firstly analyzed. a phase voltage reconstruction method is proposed that utilizes vector decomposition characteristics. Then, to suppress the effect of blind zone caused by low modulation ratio and sector boundary regions, a complementary vector strategy based on vector injection is further proposed to achieve high-quality-reconstruction. Finally, the effectiveness of the proposed method is validated on a 3 kW current source inverter.
