Circuit configuration

The utility model relates to a circuit configuration (1). The utility model relates to a method for reducing harmonics of an input current of a rectifier (10) connected to an alternating current network (N), the rectifier is used for providing DC voltage for DC voltage electric equipment (40) with a storage capacitor (C intermediate circuit). The circuit arrangement comprises a DC voltage regulator (20) connected downstream of the rectifier (10) and a regulating device (30), the regulating device is configured to impart a particular current to the DC voltage regulator (20), in particular a harmonic current signal to a waveform-similar DC current, in order to reduce harmonic components in the input current. As a result, harmonics contained in the input current can be reduced. 本实用新型涉及一种电路配置(1)，用于减少连接在交流电网(N)上的整流器(10)的输入电流的谐波，所述整流器用于为具有储存电容器(C)的直流电压用电设备(40)提供直流电压，所述电路配置包括连接在所述整流器(10)下游的直流电压调节器(20)以及调节装置(30)，所述调节装置被配置为用于为所述直流电压调节器(20)外加特别的电流，特别是为波形近似的DC电流外加谐波电流信号，从而减少所述输入电流中的谐波分量。由此，可减少输入电流中所包含的谐波。
