In this research, we aim to realize a small IoT device which is attached to an object to informatize it. In particular, our goal is to design an optical-powering system to operate the device. The principle of the operation is as follows. The system charges a capacitor with light current from solar cells, and discharges it when its voltage reaches a certain value. By repeating this operation, the system supplies power to a load intermittently.
This time, among the components of the suggested system, rectifier diodes were chosen, and an LDO regulator, which is used to flatten the voltage, was considered and designed. Therefore, the evaluation results of each components and the light-energy-harvesting system are reported. |
