Research and Design of Misalignment-Tolerant LCC–LCC Compensated IPT System With Constant-Current and Constant-Voltage Output

IEEE transactions on power electronics, 2023
It is well known that loads of inductive power transfer systems are often energy storage devices. The major benefit of an LCC–LCC compensation topology is that without the additional compensation elements and control methods, the load-independent ...

A Wireless Power Transfer System with Multiple Constant Current and Constant Voltage Outputs

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
This paper proposes a novel multi-load wireless power transfer (WPT) system with both constant current (CC) and constant voltage (CV) outputs. Repeater coils are used and every two repeater coils form a repeater unit. The bipolar coils are adopted in the proposed WPT system and the two coils in the same repeater unit are placed perpendicularly to ...
