Abstract
Drones’ technology has become forefront in the industry development sector. It has been used in many applications such as forest fire monitoring, border security surveillance and delivery application. However, drone flights are limited to only a few minutes also high current consumption by drone’s motors resulting in requiring batteries with high capacity. This represents a challenge for the drones to efficiently serve their purpose, researchers show more interest in developing a drone wireless charging method for longer flight duration. Many factors are to be considered such as power transfer efficiency, number of transmitter coils, frequency range and transfer distance; all these factors have been reviewed in this research. This paper aims to investigate and review the methods of wireless power transfer (WPT) and its capability to charge a drone’s battery at all sizes. WPT is divided into three main types which are capacitive wireless power transfer (CWPT), radiative and non-radiative methods. Non-radiative technique is divided into three methods which are inductive wireless power transfer (IWPT), hybrid capacitive wirelesses and magnetic resonant wireless power transfer. The types of wireless charging technologies based on the distance between transmitter and receiver have been summarized. The advantages and disadvantages of each method have been introduced. Hybrid inductive and capacitive method using multiple transmitter antennas is a potential technology for the charging of drone’s battery. Design of the WPT station has been proposed, which consists of four transmitters’ antennas aims to increase the output power efficiency. Performance analysis of wireless power transfer module was conducted, and efficiency was calculated based on the distance between power transmitter (Tx) and power receiver (Rx). A maximum efficiency of 98% was achieved at 0 mm between Tx and Rx, when using 20Ω as a load resistance. A minimum efficiency of 86% was achieved at 0 mm between Tx and Rx, when 35 and 50 Ω were used as a load resistance respectively. The future development and future workforce strategies were proposed.
