Abstract
Conference Title: 2017 International Conference on Sustainable Energy Engineering and Application (ICSEEA) Conference Start Date: 2017, Oct. 23 Conference End Date: 2017, Oct. 24 Conference Location: Jakarta, Indonesia This paper proposes a design of power receiving side on capacitive coupling wireless power transfer for an unmanned aerial vehicle (UAV). In order to minimize a component used in the system and fitted the circuit to the drone, the realized system must be very compact and efficient. The power receiving circuit in CPT system for simple application consists of rectifier and capacitor. In an advanced method, several components added into a circuit that makes the size and weight of the system increased. In this paper, all resonant matching system is placed and controlled in the primary side, thus the secondary side circuit could have a light module with minimum components. This paper focuses on the design a secondary side of CPT consisted of a rectifier, a DC-DC buck converter, and a charging circuit. The system is designed to operate with wide range input voltage. Simulation and experimental results have demonstrated that the proposed system could obtain charging process for Li-Ion cells battery by the output power of 8 W, with the power efficiency exceeding of 77%.
