The PCIM is an international Forum for Power electronics experts with a strong focus on the Chinese market. This important event is held to be a technical and scientific forum for engineers and researchers engaged in all fields related to power conversion technologies. The conference and Exhibition is covering power electronics in the whole value added chain from materials to components and system solutions in industry, the automotive sector and renewable energy technologies. This year again we have seen a high quality of papers submitted and selected the best and most important for inclusion in the program of oral and poster presentations. The technical program for this year's conference is high lighting advanced technologies for power semiconductor devices and passive components as well as high efficient power converters for e-mobility and renewable energy technologies. Keynote papers covering the development trend for power semiconductor devices optimized in high performance power converters and hybrid renewable energy standalone systems. In particular I am happy that we could include a special session on renewable energy and smart grid for showing future development directions. schovat popis
