有源前端变频器在船舶电力推进中的应用

Application of Active Front End Variable Speed Drive for Marine Electrical Propulsion System

介绍了国外最新的应用在船舶电力推进上的有源前端(AFE)变频器的原理及特性。相对于目前流行的多脉冲变频方案,AFE变频方案具有诸多优点,它可以从根本上解决电力推进系统的谐波干扰和电压降等问题,因此在船舶电力推进应用中前景看好。

This article introduces the principle of AFE drive on the latest diesel-electrical propulsion vessels abroad. Comparied with traditional multi-pulse drive solution, AFE drive has many advantages, especially in eliminating THD and voltage drop caused by the electrical propulsion system. So AFE drive for ship electrical propulsion has a bright future.
