碩士 === 國立成功大學 === 電機工程學系專班 === 101 === Hybrid Energy has been developed and applied in a lot of aspects for the past few years. It has become more mature and not just being limited in the use of gasoline. Hence, we should try to make good use of Hybrid Energy. The purpose of this study is to solve the unstableness of power supply when charging with Hybrid Energy, which is intermittent and unpredictable. In this study, we had implemented a Hybrid Energy System Structure as the axis of this experiment, and added related sensors to become a weighted charge structure. We had evaluated charging stability by the data from detecting the light of sunshine and the energy capacitor of PV Array relation. Therefore, we can confirm and adjust charge source at any time to complete the power storage successfully. We chosed Solar and AC as the main charging source in this experiment. Following the Solar characteristics, we used light sensor to induct the strength of sunlight, combined with DC meter to measure the Solar current. We also adopted Master-Slave structure from ZigBee to complete the data transmission. Slave as to collect the related data; Master as to do weighted analysis and comparison that can help to decide which Hybrid Energy is more suitable. Then, Master can transmit the controlled signals to Slave and to control the power path, in addition to that switching to the chosen kind of energy automatically. Data shows, the light of sunshine and the strength of current are mutual related. And it will switch automatically when reach a conditioned threshold.
