Modeling Analysis of Wireless Power Transmission (WPT) System with LCCL-LCL Compensation Network

This paper proposed a wireless power transfer (WPT) systems with LCCL-LCL compensation network. Firstly, modeling the T-type compensation network has been analyzed for its constant voltage (CV), constant current (CC), and zero phase angle (ZPA). On this basis, working principle and operational characteristics of LCCL-LCL compensation network was shown and influence of mutual inductance, load and parasitic resistance was analyzed in detail. Additionally, the effectiveness of the proposed LCCL-LCL compensation network is verified with different operating conditions, such as load short circuit, secondary side loss, and load open circuit. The objective of these investigations is to analyze the effects of parameters on power transmission, consequently providing essential insights for designing parameters of LCCL-LCL compensation network in WPT systems.
