资料介绍

为降低加速器直流励磁电源的输出电流纹波,研究了一种抑制电源输出电流纹波的直流有源滤波器(DAF)。采用检测负载电压的方式,解决了电流纹波幅值小难以检测的问题。通过控制DAF吸收或注入谐波电流来降低电压纹波,进而达到降低电流纹波的目的。设计的buck/boost电路作为有源滤波器的主电路,能维持储能电容电压的稳定,省去了整流电路。对设计方案进行了仿真并搭建了实验样机进行验证,实验结果表明,设计的DAF对低频纹波有一定的抑制效果。

In order to reduce the output current ripple of the accelerator DC excitation power supply,a DC active filter(DAF)for suppressing output current ripple of power supply was ng the method of detecting the load voltage,the problem that the current ripple amplitude is very small and difficult to detect was objective voltage ripple was reduced by controlling the DAF to inject or absorb harmonic current,and the purpose of reducing the current ripple was buck/boost circuit was designed as the main circuit of the active filter,which can maintain the stability of the storage capacitor voltage and eliminate the rectifier design was simulated and an experimental prototype for verification ...
