    Abstract: 本論文旨在研究和解決電源於輕載時,效率非最佳化的問題。
    一般電源供應器設計考量以最重載為主。但實際實用上,大部份時間,電源操作在中載或輕載,如PC 500W的電源,大部份時間操作於130~250W,而愈輕載操作時,其效率將愈低。
    ;This thesis aims to study and solve the power supply efficiency problem that occurs during non-optimization usage.
    The power supply design was built for full load power, however most of the time the power contained in the operation is light load or middle load. For example, a PC 500W power supply often operates at 130 ~ 250W. Therefore, if the power supply is not running at or near full capacity, the level of efficiency is not satisfactory.
    To solve the light load and the middle load issues, designers generally use mutation mode control to reduce switching losses and improve efficiency. Although, traditional mutation patterns can lead to unstable output. The output ripple is too large when using mutation mode control, and light-load efficiency is not optimized.
    This article is a non-conductive time modulation study focused on reducing the problem of oversized output ripples and the use of the three-pulse mode control to fix unstable output and optimize light load efficiency.
    In this particular thesis we utilize the PSU component NXP1916 to verify that the light load improves efficiency.
