It is an effective method to mitigate the negative effects caused by modern inverters to fit the filters at the inverter output terminals. In this paper, a simplified design principle based on the typical sample parameters of the commercially available inverter output filters is proposed. The spline functions of the inductance and the capacitance with some coefficients are built firstly according to the topology of the filter and the practical considerations. Then, the optimizations of the functions are carried out by means of the typical sample filter so that the useful design functions for some series of filters are obtained. The experiment cost will be reduced or avoided because the practical samples of the filters are applied so that the design results will be more suitable for actual situations. A 3kVA prototype is completed to confirm the validity of the method proposed in this paper.
