| Summary: | 碩士 === 國立勤益科技大學 === 電機工程系 === 104 === The purpose of this paper is to perform the design and implementation of a high step-up bidirectional converter for photovoltaic power generation systems. The system architecture includes a maximum power point tracking controller and high step-up bidirectional converter. In order to make photovoltaic power generation system, under different sunlight can reach the maximum power output. We use maximum power point tracking controller as the control. For keeping the voltage dynamic response of load step change with the features of zero steady-state error, no overshoot, small voltage-drop and fast restore time. So we perform the quantitative design of a controller by the given performance specification. First, we use the step response estimation method at the selected operation point to estimate the dynamic model of the converter. Then, depend on the given load regulation performance to make the quantitative design of controller’s parameters. It enable the converter’s output DC link voltage be controlled at the planned dynamic and steady-state response performance with stable energy supply. Finally, we use the measured results to verify the performance of the designed controller.
