摘　　要：为满足强磁场装置电源供电极低的电流纹波要求,采用了有源滤波装置,设计了一种新型的双向DC/DC变换器取代了以往有源电力滤波器(APF)中使用的水冷电阻,将多余能量回馈给系统,从而大大节约了能量损耗。首先简述了当今各种有源滤波技术的优缺点,并介绍了并联型线性APF的工作原理,接着详细分析了双向DC/DC变换器的控制方案设计原理与工作过程,最后对该设计方案进行了仿真与实验验证。由实验波形可知,该双向DC/DC变换器能够顺利实现能量的双向流通。An active power filter（APF） is adopted in order to meet the requirements of extreme low current ripple for the power supply of high magnetic field device.A kind of new bi-directional DC/DC converter is described to replace the water cooled resistor which used in the APF.The excessive energy can be fed back to the system ,thus energy loss can be reduced greatly.The advantages and disadvantages of various active power filtering technology are described and the working principle of shunt linear APF is analyzed, then the design control principle and the working process of bi-directional DC/DC converter are described in detail.Finally,the design scheme is simulated and verified. The experimental waveforms show that the bi-directional DC/DC converter can work normally and realize the bi-directional flow of energy.
