Two papers from AEPCL are accepted by WoW 2020
WoW 2020 is one of the leading IEEE conferences focus on wireless power technologies, and will be held during May 5-9, 2020, at Seoul, Korea. This conference provides the best international workshop to present and discuss the progresses in research and development of wireless power technologies, including the design of power transmitters and receivers, applications, control strategies and other devices, system and technologies related to wireless power.
Two papers from AEPCL are accepted by WoW as below:
G. Ning, P. Zhao, R. He and M. Fu, “A Novel Passive Current Sharing Method for a Two-Receiver-Coil IPT System”, IEEE Wireless Power Week,Seoul, Korea, May 5-9, 2020.
A two-receiver-coil system could enhance the output power capability and help reduce the conduction losses. However, the unequal coupling would affect the current distribution. In this paper, a novel passive current sharing method is proposed for a two-receiver-coil system. Automatic current sharing is achieved by adding a path between the two receiver coils. The current sharing performance is evaluated through the circuit analytical model. The proposed method can automatically balance the output currents without additional active circuits and control strategy. A 10-W one-transmitter-coil two-receiver-coil system is built to verify the balancing effects.
R. He, G. Ning and M.Fu, “A D4Q Pad with High Misalignment Tolerance for Inductive Power Transfer System”, IEEE Wireless Power Week, Seoul, Korea, May 5-9, 2020.
This paper proposes a three-transmitting-coil IPT system to improve the misalignment tolerance. In order to decouple the transmitting coils, a novel three-coil structure is explored to fully utilize the benefits of symmetric structure. In this paper, different coil structure, such as circular pad, double D(DD) pad, and double D quadrature (DDQ), are studied to evaluate the decoupling mechanism and compare the misalignment tolerance. Finally, a novel D4Q planar charging pad is developed to improve the misalignment tolerancein a horizontal plane. The Maxwell-based simulation is used for verification. It shows the effective charging area of the proposed D4Q pad is improved by 6% compared to the DDQ pad.
