Chen, Minggang (author), Zhang, H. (author), Fan, Q. (author)Silicon MOSFETs-based medium-power (< 50W) Class-D amplifiers (CDAs) switching in the MHz range have gained popularity in recent years, which achieves better linearity thanks to a higher loop gain in the audio band while enabling the use of LC filters with higher cut-off frequencies. However, for high-power (>100 W) CDAs, such switching...conference paper 2023

Sun, Yubo (author), Chen, B. (author), Zhang, Shizhe (author), Blom, Kees (author), Lukovic, M. (author), Ye, G. (author)In recent years, the rapid industrialization and urbanization led to the explosive growth of municipal solid waste incineration (MSWI) bottom ashes (BA) production. However, most of them are directly landfilled, which not only brings environmental burden but also results in loss of potential resources. Present researches have proved that MSWI BA...conference paper 2021
