Device for suppressing DC component in inverter output current e.g. via solar generator, into public network, includes controller for controlling switching processes of inverter depending on measured integral DC component

摘要

A device for suppressing a DC component in the output current of inverters has a measuring device (Cm, 4) for integrating measurement of the DC component in an output conductor of the inverter, and a controller (4) for controlling the switching processes of the inverter depending on an integral DC component measured by the measuring device (Cm, 4), so that the integral DC component is compensated in the output conductor. An Independent claim is included for method of suppressing a DC component.
