Analysis of Contactless Power Transfer System Using Generalized State Space Averaging Method

摘要:

采用广义状态空间平均法(GSSA)基于频域分解的思想将系统非线性模型近似成线性连续模型，并依据该模型分析了非接触电能传输技术(CPT)系统的稳态和暂态过程.仿真结果表明，GSSA模型能较快地完成对CPT系统的稳态及暂态分析，且与Simulink创建的精确时域模型的仿真结果一致.在此基础上，给出了系统效率计算方法，分析了直流电感、负载参数对系统效率的影响.

Abstract:

According to system switching nonlinear characteristic,the paper utilizes generalized state space averaging (GSSA) method,decomposes system model in frequency domain and transform system nonlinear model to approximate linear continuous model.With the model,system static and transient dynamic behaviors are analyzed in detail.Simulation results are consistent with SIMULINK model.Furthermore,system efficiency computing method is presented.And analyses among system efficiency,DC inductor and load parameters are proposed for system design as well.
