| Abstract |
Design approach and control strategy have a significant impact on the performance of the wireless power transfer systems in electric vehicles powertrains in terms of efficiency, charging power, charging modes (i.e. G2V and V2G) and charging time, etc. Thus, this paper proposes new design methodology and control system for a bidirectional 3.7 kW wireless power-transfer (WPT) of light-duty electric vehicles (EVs); operating at frequency 85 kHz and at frequency 140 kHz. In this paper, Series/Series (SS) WPT compensation topology is optimally designed and controlled for G2V and V2G modes using MATLAB/Simulink. A simulation study is performed for a selected WPT for both G2V and V2G operating modes to ensure its functionality and performance at different switching frequencies. Moreover, the impact on the grid quality is investigated for both operation modes. |
