摘要

在电池充电过程中选择合适的充电算法并保持系统高效率是决定无线电力传输系统性能的重要因素之一。通过使用不增加控制系统复杂性的方法来提高效率有助于这些系统的工业化。本文提出了一种串联补偿、功率为150W的恒功率恒压充电系统，该系统在二次侧采用半有源整流器(SAR)和开关控制电容器(SCC)，而不需要在发射端和接收端之间连接，从而在恒功率恒压充电过程中保持较高的效率。

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.
