碩士 === 國立聯合大學 === 電機工程學系碩士班 === 104 === This thesis is to implement that the PV modules supplied an interleaved high step-up DC/DC converter. The output voltage of the interleaved high step-up DC/DC converter supplied to a DC/AC single-phase inveter and a DC/AC three-phase inverter. Then, the output power of the inverter is provided to drive signle-phase induction motor and three-phase induction motor. The interleaved high set-up DC/DC converter adopted an adjustable coil turns of coupled inductance to enhance high voltage ratio. Additionally, the interleaved high step-up DC/DC converter has some advantages such as reduction of output current ripple, reduction of step-up inductance, reduction of voltage stree in the output capacitor and step-up switched frequency to speed-up response of the system. Meanwhile, the power switching can be adopted the lower voltage and lower conduct loss to enhance the whole efficiency. The adopted three closed-loop feedback controllers of the interleaved high step-up DC/DC converter are the the proportional-integral (PI) controller, the fuzzy controller, and the fuzzy theory-based parameters adjustment of PI controller. The DC/AC single-phase inveter adopts the unipolar sinusoidal pulse width modulation (SPWM) to drive a signle-phase induction motor. The DC/AC three-phase inveter adopts the space vector pulse-width-modulation (SVPWM) technology to drive a three-phase induction motor. All control methods are realized by using the TI TMS320F28335 digital signal processor（DSP）.
