摘　　要：主要分析新型24脉波中频整流电源的整流原理,讨论网侧的谐波特性。利用MATLAB分析软件,根据实际设备参数分别对采用24脉波整流装置的中频电源与采用传统12脉波整流装置的中频电源进行建模,验证中频电源的谐波特性。仿真结果表明多相整流技术可使中频炉流入电网的谐波含量大大下降,有效改善输出波形。In this paper, the working principle of new 24-pulse medium-frequency rectifier power sup- ply was analyzed. And the harmonic characteristics of the power networks were discussed. Based on the practical device parameters, the models of 24-pulse rectifier and traditional 12-pulse rectifier of the medi- um frequency power supply were built by using MATLAB. The simulation results showed that the het- erogeneity rectification technology can greatly reduce harmonics, and improve output waveform.
