主　　题：phase-shift angle autotransformer 12-pulse rectification system Matlab analysis 

摘      要：Based on the study of the harmonic suppression on DC side of the multi-pulse rectification system,a software platform is established in Matlab *** phase-shift angle is studied from the aspects of system stability and economy,analyzing the effects of phase-shift angle on the input-side line current,the output-side voltage ripple,the equivalent capacity of autotransformer and other auxiliary devices in 12-pulse rectifier *** software platform can complete the analysis only by inputting the initial conditions,eliminating the derivation of the intermediate formula and reducing the complexity of the system analysis,and have good *** simulation results show that the system can effectively analyze the influence of phase angle on 12-pulse star-connected transformer.
