摘　　要：为抑制电气化铁道产生的谐波,在详细分析其形成特点的基础上,基于基波磁通补偿的原理,提出了一种串联型有源滤波器方案。同时,在设计无源滤波部分时兼顾无功补偿。实验和仿真结果表明此方案具有很好的实用性。To suppress harmonic currents caused by electric locomotive,a high power series active power filter based on the fundamental magnetic flux compensation of the series transformer is designed.In order to decrease the power of inverters,a novel transformer structure with multiple secondary windings is proposed.The multiple pulse-width modu- lation (PWM) inverters are connected with the multiple secondary winding,respectively.The PWM inverters produce fundamental currents that are respectively injected into the corresponding compensation secondary windings.In this way,the power of inverters are reduced.The viability of the filter is verified by an experimental setup of 30kVA and simulated result of 10.000kVA.
