Ideally,converter losses should be determined without using an excessive amount of simulation ***-of-the-art power semiconductor models provide good accuracy,unfortunately they often require a very long simulation *** paper describes how to estimate power losses from simulation using ideal switches combined with measured power loss *** semiconductor behavior is put into a look-up table,which replaces the advanced semiconductor models and shortens the simulation *** extract switching and conduction losses,a converter is simulated and the semiconductor power losses are *** results on a laboratory converter are compared with the estimated losses and a good agreement is *** the ideal switch simulation and the post processing power estimation program,a ten to twenty fold increase in simulation speed is obtained,compared to simulations using advanced models of semiconductors.

TiO2 -Au aerogels containing different amounts of gold nanoparticles of different sizes (5 and 16 nm) were successfully synthesized using a sol-gel procedure, and were tested for salicylic acid photodegradation under UV irradiation. The structure and morphology of the obtained materials were investigated using X-ray diffraction, transmission electron microscopy, and n2 adsorption-desorption measurements. UV-Vis spectroscopy was used to study the optical properties. The effects of the gold nanoparticles on the TiO2 crystallization process were twofold, as follows: (i) the number of crystallized zones was strongly related to the concentration of the gold nanoparticles, and (ii) the smaller gold particles increased the time taken for the crystallization of the samples. It was found that the noble metal-doped samples exhibited higher degradation rates compared with bare titania. It was found that the most active photocatalyst in each studied system was the sample with the highest concentration of gold nanoparticles. Additionally, the highest degradation rate value was obtained with the smallest Au nanoparticles (46.4 10-3 μmol/(L·s).
