Design of Non-Communication Based WPT Battery Charging System With CP-CV Method

Choosing the appropriate charging algorithm and keeping the system efficiency high during the battery charging process is one of the most important factors determining the performance of wireless power transmission (WPT) systems. Increasing efficiency by using methods that do not increase the complexity of the control system can help industrialize these systems. The present paper proposes a WPT system with series-series compensation and power of 150W, which keeps the efficiency at a high level during the constant power constant voltage (CP-CV) charging process, using a semi-active rectifier (SAR) and a switch-controlled capacitor (SCC) in the secondary side, without the need for a connection between the transmitter and receiver side.
