USS029  |  Free Piston Internal Combustion Engine

Traditional small internal combustion engine systems have many drawbacks including limited operational optimisation possibilities, low efficiency and low power-to-weight ratio. Previous free-piston engine developments have been designed with 2-stroke ‘ported-valve’ arrangements, and therefore suffered from poor fuel efficiency and high exhaust gas emissions. Another challenge for previous free-piston engine developments is related to piston motion control.

USS048  |  Smart Power Management Unit (SPMU) for Renewable Generations and DC Microgrid

Recent years, the clean energy industry has seen dazzling growth, especially in solar and wind generation. According to a report from International Energy Agency (IEA), renewable energy will represent the largest single source of electricity growth over the next five years. Renewable electricity additions over the next five years will top 700 gigawatts (GW). They will account for almost two-thirds of net additions to global power capacity. The technology described herein is related to a highly scalable DC microgrid system which accommodates multiple sources of renewable energy generation and provides loading sharing control strategy.
