摘要
随着科技的发展,人们的生活节奏加快,对手机等移动设备的使用频率不断提升,使得普通的无线充电方案已经无法满足使用需求。因此,效率高且干扰小的无线快速充电方案急需走进人们的生活。DC/DC调压是一种能够实现电压数字可控的调压方式,因其效率高和稳定性好等优点被广泛应用。基于DC/DC调压原理分别设计出两种应用于无线快速充电的定频调压方案,并对电路参数设置进行理论推导,最后对设计的方案进行实现。性能测试及样板充电实验验证了理论推导和方案设计的正确性和有效性,表明其具有重要应用价值。
With the development of technology,people′s life rhythm is accelerating,thereby increasing the frequency of using mobile phones and making the previous wireless charging solutions unable to meet people′s needs.Therefore,fast wireless charging solutions with high efficiency and low interference are desirable in people′s lives.DC/DC voltage regulation can achieve digitally controllable voltage,and is widely used because of its high efficiency and good stability.Based on the principle of DC/DC voltage regulation,this paper designs two fixed frequency voltage regulation schemes for fast wireless charging,theoretically derives parameter settings in the circuits,and finally implements them according to the designed schemes.Performance tests and model experiments validate the correctness and effectiveness of the theoretical derivations and scheme designs,and indicate the proposed schemes have important application value.
