Abstract

Mobility, continuity and safety are crucial in charging and discharging system of electric vehicles (EV) in smart grid applications. Bidirectional inductive wireless power transfer (BIWPT) system is ideal choice for these services. With accurate and efficient system models in hand, the circuit designers can predict and optimize the system performance. In this paper, an accurate, intuitive, and comprehensive steady-state theoretical model is proposed and implemented in MatLab environment. This model is generalized and can be used for any magnetic design of BIWPT system with the same compensation topology. The model is able to predict the system currents, voltages, power, power factor and equivalent impedance. The proposed model is used to evaluate two different designs for LCL compensation topology based on impedance frequency response analysis. Also, general considerations for the filters design parameters are stated and verified in this paper. A Simulink MatLab model for 1 kW BIWPT system is built to verify the proposed theoretical analysis.

基于谐波的V2G双向感应无线电力传输系统稳态数学模型

在智能电网应用中，电动汽车充放电系统的移动性、连续性和安全性至关重要。双向感应无线电力传输(BIWPT)系统是这些服务的理想选择。有了准确有效的系统模型，电路设计人员就可以预测和优化系统性能。本文提出了一个准确、直观、全面的稳态理论模型，并在MatLab环境下实现。该模型具有推广意义，可用于具有相同补偿拓扑结构的任何双水冷发电系统的磁设计。该模型能够预测系统的电流、电压、功率、功率因数和等效阻抗。利用该模型对两种基于阻抗频响分析的LCL补偿拓扑设计进行了评价。此外，本文还阐述并验证了滤波器设计参数的一般考虑因素。为验证所提出的理论分析，建立了1kw BIWPT系统的Simulink MatLab模型。
