The invention relates to an apparatus for delivering electrical power, in particular for delivering regeneratively produced electrical power, which has at least one converter (5, 6, 11, 12) and at least one filter (7, 8, 9, 14a, 14) for adapting the delivery of power by the converter to a load impedance. The problem addressed by the present invention, that of providing an apparatus for delivering electrical power and a corresponding method for operating an apparatus for delivering electrical power which allows improved monitoring of the method of operation of the filters or mains filters, is solved for an apparatus by providing means (7', 8', 9', 14a', 14') for determining at least one filter current in at least one filter, which means are designed in such a manner that said means make it possible to determine the at least one filter current during operation of the apparatus, wherein comparison means are provided and generate an error information signal using the desired value and actual value of the filter current and a predefinable error criterion. |
