报告摘要：

Nowadays, high-voltage power conversion integrated circuits have found wide applications in automotive systems, industrial and telecom systems, and renewable energy systems. Innovation in the high-voltage power converter design through miniaturization is important as it can lead to significant system cost reduction. However, state-of-the-art high-voltage power converters typically require the use of large-value bulky passive components due to the limitation of low-frequency hard-switching operation. In this talk, we will first examine different power losses of state-of-the-art high-voltage power converters and explore high-frequency zero-voltage switching technique for improving the converter power efficiency and reducing required values of passive components. We will then discuss both closed-loop automatic dead-time control and high-speed level shifting technique in high-voltage on-chip gate drivers to enable high-frequency reliable zero-voltage switching in high-voltage power converters. With above techniques, the design of a high-voltage DC-DC based dimmable LED driver with a CMOS power train will be presented as a design example.
