Maximum Power Efficiency Tracking for UWPT

In this chapter, an adaptive control strategy called maximum power efficiency tracking (MPET) is presented. MPET improves the efficiency of the UWPT system without any direct output feedback. Usually, a wireless communication system is often required to send output power feedback signal to the input circuit. However, such feedback will require wired or Wi-Fi communication which is not viable in an underwater water environment. In the presented control method, the control is deployed on the secondary side of the system using a DC/DC converter.
