摘要
针对电蚊拍储能电池充电时间长、易损坏、使用寿命短的问题,提出了一种基于超级电容器储能式电蚊拍的应用电路设计方案。采用超级电容器单体过压保护芯片BW6101构成的开关电阻式电压均衡5 V超级电容器模组来代替电蚊拍的储能电池,并经过DC/DC升压转换芯片TPS61220来保证电源电路有稳定输出电压。通过电路性能测试,确定该方案的可行性,最终完成充电时间短、使用寿命长的超级电容器储能式电蚊拍的应用设计。
For the problems of long charging time, easy dama g e and short life of the electric mosquito swatter battery , a circuit design based on super-capacitor energy storage is put forward. It takes the switch resistance type voltage balance of 5 V super-capacitor module which is composed of the overvoltage protection chip BW 6101 to replace the energy storage battery of electric mosquito swatter , and then usesthe DC/DC converter TP S61220 to ensure stable output voltage for the power circuit. The scheme isfeasible through by the circuit performance test , and it ultimately achieves the desigcapacitor energy storage type of electric mosquito swatter with short charging time and long life.
