Encryption is a very important technique used to protect energy transmission channels from unauthorized receiver. It can be utilized to transmit data securely over the wireless medium. Encryption techniques of wireless power transfer (WPT) are important in the research on the effects of security key for security of energy transfer to the authorized receiver. The energy encryption scheme of WPT is proposed to chaos theory. Chaos theory is applicable to the logistic map to propose as a security key to chaotically regulate the switching frequency. Furthermore, chaos theory characteristic affects power and distance performance. Therefore, this paper investigates mainly effective power based on mobile charging application. This research is focusing on the performance of energy encryption in medium field for wireless power transfer system by optimization switching frequency. This research is dedicated to the performance of energy encryption for medium field wireless power transfer system based on mobile charging application. The optimization to transport the power in this research based on power is 10 W. The research utilized MATLAB simulation to compare the performance.
