Predicting semiconductor and inductor losses together with designing the EMC filter for grid feeding inverters requires great effort, when high and variable pulse frequencies and triangular current mode are applied. In this paper an effective method is proposed to quickly evaluate the effect of circuit and control strategy on losses and inverter size. With this approach the system is modeled using only a few representative operation points, which leads to a significant effort reduction. The approach is validated on a 2 kW 1-phase DC-AC converter according to the requirements of 'The Google/IEEE PELS Little Box Challenge'.
