Approximative Estimation of EMI Mains Filters Properties in the "Worst-Case" System Operation

Original language description

One of the main problems in the design of mains line EMI filters is the uncertainty and ambiguity of their source and load impedances. As these impedances act namely the HF supply network impedance on the one hand, and the HF input impedance on the powerinput terminal of the protected equipment on the other hand. In the usually operating frequency range from 10 kHz to 30 MHz, both impedances are variable from some tenth Ohms to some hundreds of Ohms, and they are very substantially depended on the typee, construction, and instantaneous load of the mains line network, in which the filter should be used. Since the insertion loss of an EMI line filter is dependent on the source and load impedances, most filter manufacturers provide the filter design forthe matched 50 Ohms impedance system. From the above reasons of course, this may not give proper and estimated results in real mains line networks installation. The paper presents a new technique for so-called "worst-case" EMI filter desi
