The invention relates to the technical field of wireless power transmission, and particularly discloses a parameter design method of a bilateral LCC compensation BIPT system, which aims at solving the problem that the power and efficiency of the system are reduced due to the fact that the existing bilateral LCC compensation network-based BIPT system is designed to be in parameter symmetry but the parameters of an LCC compensation network in an actual system are asymmetric. The method comprises the following steps: firstly, defining asymmetric parameter factors including parameters such as an inductance ratio alpha p of a self-inductance Lp of a primary side coil and a compensation inductance Lrp of the primary side coil, an inductance ratio alpha s of a self-inductance Ls of a secondary side coil and a compensation inductance Lrs of the secondary side coil, a primary side and secondary side compensation inductance ratio beta, a ratio T of primary side and secondary side excitation voltages, a quality factor Q of transmission efficiency, an equivalent quality factor Qr of an inductance branch and the like; the method comprises the following steps of: firstly, deducing the relationship between the efficiency and the output power of the system during forward and reverse transmission and the parameters, and finally, designing the parameters during forward and reverse transmission based on the relationship between the efficiency and the output power of the system and the parameters, so that the requirements of the system on the output power and the transmission efficiency can be met.

    本发明涉及无线电能传输技术领域,具体公开了一种双边LCC补偿的BIPT系统的参数设计方法,针对现有的基于双边LCC补偿网络的BIPT系统设计为参数对称,但实际系统中LCC补偿网络的参数会不对称,导致系统功率和效率下降的问题,首先定义了不对称参数因子包括原边线圈的自感Lp与其补偿电感Lrp的电感比αp、副边线圈的自感Ls与其补偿电感Lrs的电感比αs、原副边补偿电感比为β、原副边激励电压的比值T、传输效率的品质因数Q、电感支路的等效品质因数Qr等参数,然后推导了系统正向和反向传输时的效率、输出功率与这些参数之间的关系,最后基于系统效率、输出功率与这些参数之间的关系设计正向和反向传输时的这些参数,能够满足系统输出功率、传输效率需求。
