Constant current and constant voltage output WPT system based on LCC compensation network
2020 IEEE International Conference on Mechatronics and Automation (ICMA), 2020In this paper, the LCC compensation network is applied in the MCR-WPT system to achieve constant voltage and constant current characteristics which is required for battery charging. The configuration and parameters of the LCC network are obtained through the analysis of the working principle.

A Wireless Power Transfer System with Multiple Constant Current and Constant Voltage Outputs
2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019This 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 ...

Output voltage constant control of three-phase Z-source inverter
2012 IEEE International Symposium on Industrial Electronics, 2012This paper proposes a new constant control method of the output voltage of a voltage-fed three phase Z-source inverter (ZSI), in case of the capacitor voltage variations in Z-source network or the heavy changes of load. The modulation index for the reference output voltage of the ZSI can be calculated by the basic definition of the ZSI, the input DC ...

Class E circuit has the advantages of less components, high reliability and soft switching, hut the traditional Class E circuit can only he used in low power condition because of the unidirectional excitation. In order to extend the power range, this paper proposes a novel hybrid Class E circuit, which can be operated at high power.
