摘要

This study proposes a practical passivity-based control (PBC) strategy of the hybrid rectifier based on Vienna and single switch three-phase boost (SSTPB) rectifiers. For medium and high application, the SSTPB rectifier operates at higher output power state with low frequency, the Vienna rectifier operates at power quality improvement state with high frequency, and the hybrid rectifier has the advantages of perfect sinusoidal input currents, unity power factor, high reliability, high efficiency and low cost. PBC is stable globally and has strong robustness to internal and external interference with less parameters and PBC of the hybrid rectifier has the advantages of less parameters, good dynamic characteristic, high current control precision and strong robustness. The detailed mathematical model based on Euler-Lagrange is built, the sixth harmonic current injection strategy is proposed, and the PBC controller is designed by damping injecting method in the study, and simulation results in SIMULINK are also given. At last, a down-sized hybrid rectifier prototype is built and the experimental results verify correctness and effectiveness of the proposed solution and analysis.
