Abstract: For the high-power hybrid-clamped three-level rectifier,its working principle is analyzed,the mathematical model of the hybrid-clamped three-level rectifier under a,b,c stationary coordinate is deduced in detail,the mathematical model under two-phase rotating coordinate is obtained after coordinate transformation.The direct current control strategy based on the orientation of the grid voltage is employed for the rectifier.The simulation model is built in matlab,and the relevant experiment is completed.The correctness of the mathematical model and the effectiveness of the control strategy are verified by the simulation and experiment.
