摘要
有源前端(AFE)在船舶电力推进变频器中有较为广泛的应用,AEF具有功率因数校正功能,且具有好的电流谐波特性,允许功率双向流动,可以去除制动电阻,节约成本。文章在MATLAB/Simulink中搭建了带有源前端的变频器仿真模型,拖动异步推进电机,取得良好的控制效果。
Active Front End （AFE） rectifer has a wide range of applications in Marine Electric Propulsion frequency converter. AEF has power factor correction fimction, and good current harmonics characteristics. Because the active front end rectifier is a bi-directional power flow rectifier, the braking resistor can be removed and the cost can be reduced. In this paper, the electric propulsion simulation model of the frequency converter with AFE rectifier and asynchronous propulsion motor is built under MA TLAB / Simulink software. The control effect is excellent with this simulation model.
