Study on harmonics suppression of high-power rectification circuit Based on Saber Simulation

摘要

It analyzed the quantity of differ-harmonic in the output from vary pulse rectification circuit. Considering the problems of great voltage fluctuation and high harmonics content in the rectification output under the direct-supply of current source mode, put forward the method of 12-pulse rectification circuit with equilibrium rector circuit with equilibrium reactor into direct-supply of current source mode. From the simulation results it can be summarized that 12-pulse rectification circuit with equilibrium reactor can not only smooth the output but also suppressing the harmonics.
