【摘要】：为了减少感应式无线充电系统增加的额外电路和控制成本,取消初级侧和次级侧之间的通信,该文提出仅需增加一个额外电容和一个开关器件在次级电路的方法,即可实现对电池恒流恒压切换充电。该方法无需初级和次级电路进行通信或增加DC-DC变换器,降低了整个系统的成本和复杂性。首先分析得到感应式无线充电系统的电流和电压增益,接着通过设计电路中元件参数值使得电流和电压增益与负载无关,最后合理配置电路参数,通过切换开关即可实现恒流和恒压切换输出。实验表明,所提出的方法在恒流和恒压模式下,系统的恒流充电电流和恒压充电电压略微受到电池等效负载改变的影响,但是结果仍然满足对电动自行车的充电要求。
[Abstract]:In order to reduce the additional circuit and control costs of the inductive wireless charging system, the communication between the primary and secondary sides is cancelled. This paper presents a method of adding only one extra capacitor and one switch device in the secondary circuit. The battery can be switched and charged with constant current and constant voltage. This method does not need primary and secondary circuits to communicate or add DC-DC converter. The cost and complexity of the whole system are reduced. Firstly, the current and voltage gain of the inductive wireless charging system is obtained, and then the current and voltage gain is independent of the load through the design of the component parameters in the circuit. Finally, the circuit parameters can be configured reasonably and the output of constant current and constant voltage can be realized by switching switch. Experiments show that the proposed method is in constant current and constant voltage mode. The constant current charging current and constant voltage charge voltage of the system are slightly affected by the battery equivalent load change, but the results still meet the charging requirements of the electric bicycle.
