碩士 / 國立成功大學 / 電機工程學系專班 / 98 / The design and implementation of grid-connected type inverter for tidal current power generation system is presented in this thesis. The output voltage would be stable in the default variation of input voltage. Because the input voltage will be varied in certain range, so a control procedure is made to reduce the influence to output voltage. Under stand-alone mode, the voltage feedback control is used to adjust the duty of pulse-width modulation and maintain output voltage in the default range. Under grid-connected mode, the current feedback control is used to limit output current for the purpose of output power control. Finally, the experimental result and PSIM simulation are presented to verify the control theorem and design procedure of inverter, and efficiency of inverter could be more the 91% under stand-alone mode.
