摘要
A device for the active filtering of a distorted voltage waveform 7 containing harmonics has the aim of generating a specified test voltage using a voltage link inverter. A link DC voltage occurring between the positive link voltage rail 12 and the negative voltage rail 13 formed by a rectifier stage 11 connected on the input side parallel to the source voltage lying between the input terminals 5,6 of the device is applied at the input of an inverter stage 14 corresponding to the basic structure of a voltage link converter. The correction voltage generated between the outputs 15,23 of the inverter stage is joined in series with the source voltage via the connecting wire 16.
