Design of Wireless In-Wheel Motor Drive With S/CP Compensation
(rehearsal talk for IEEE ISCAS 2024)
Mr Felix Chen, City University of Hong Kong
Abstract:This talk introduces a wireless in-wheel motor drive system based on the series/capacitor-parallel (S/CP) compensation topology. Despite the structural similarity with the conventional series/series-parallel (S/SP) circuit, the S/CP compensation embraces a different design concept to enhance the voltage gain flexibility. The study examines the input impedance and voltage gain characteristics of the system across all load and misalignment conditions. Subsequently, a novel design method is proposed to facilitate soft switching and ensure compliance with the bus voltage requirement. Consequently, the proposed design method could avoid wireless communication and additional DC/DC converters. Finally, a 600 W prototype is constructed to validate the above analysis, yielding a remarkable maximum efficiency of 96.81%.
