    Abstract: 本文主旨為研究太陽能光電系統與市電經功率因數修正
    電系統[1]中,在最大功率追蹤器後端仍需串聯一級DC/DC 轉
    This thesis focuses on the research study of a DC power
    system fed by utility with a power factor corrector (PFC) and a
    photovoltaic (PV) system parallel-connected at DC side. In
    conventional system, an additional DC/DC converter is required
    following the maximum power point tracking (MPPT) circuit in
    order to be parallel-connected with the PFC. This additional stage
    will increase the system power loss, thus cause this approach
    improper for high efficiency and low power loss requirements.
    Therefore, this thesis will, based on the basic methodology of the
    existing one, propose and study a single-stage DC power supply
    system by paralleling the utility-PFC and the PV system at DC
    side.The topology and control method for MPPT and PFC are
    discussed. The output port of the PV system is connected to the
    output of the PFC at different voltage levels. Then, the operating
    conditions for the presented single-stage DC power supply system
    are deduced and analyzed. Experimental results show the
    feasibility of the proposed single-stage topology, which can
    effectively transfer the tracked maximum power from the PV
    system to the load.
