碩士 === 國立東華大學 === 電機工程學系 === 94 === Stand-alone regenerative power systems usually require batteries for energy storage. This thesis presents the design of the battery charger powered by both the photovoltaic (PV) module and the wind turbine generator (WTG). In the power converters, a single-ended primary inductance converter (SEPIC) is adopted. This is because the SEPIC has the features of the buck-boost operating mode, no polarity inversion, low input current pulsation, and wide input voltage range. This thesis develops the following techniques: (i) Design of the current-mode control SEPIC with the input voltage regulation. (ii) Maximum power point tracking (MPPT) controller design of the PV module. (iii) MPPT controller design of the WTG without sensing the rotor parameters. (iv) Design of the three-stage battery charging controller. (v) Power balance strategy among two subsystems, the battery and the load. (vi) The PV module emulator and the WTG emulator implemented with the half-bridge converters. The MPPT controller for both subsystems, the I-V characteristic of the PV module emulator and the P-
