  • Power electronic technology in wind generation system of variable speed-constant frequency
    Direct-drive-based (no gear box) AC- DC -AC full power type VSCF wind power generation system uses a multi- polar low-speed permanent magnet or synchronous generator excitation power, while eliminating the gearbox, but the size of motor is very bulky.
  • Wind Energy Conversion Systems
    The tidal power generation system consists of an induction generator /motor connected to a DC capacitor link through an insu- lated-gate bi- polar –transistor (IGBT) bi-directional converter.
  • Six mode control strategy for a stand-alone hybrid power system
    The wind power generation module is constituted of a windmill, a multi polar permanent-magnet synchronous generator (PMSG), a rectifier, and a dc /dc converter to interface the generator with the dc bus.
  • Prediction on future DC power system
    Furthermore, to a full DC power system, multi-phase generator technology should be recommended, so that multi-phase rectifier may just be matched, even connected in an integral with only two polar -terminals out of the shell.
