摘要
为解决不间断电源超级电容等效内阻随SOC变化而影响充电效率的问题,文中采用BUCK型充电电路,针对该电路推导出不同情况下输入输出电压关系,在此基础上建立充电电路模型和充电数学模型。提出定值比较控制模式,根据建立的模型,在Proteus中建立仿真模型,通过ANALOGUE图表观察充电电流曲线,验证了定量比较控制模式的在充电速度以及效率上的明显优势。
In order to prevent the losses caused by production equipment downtime,uninterruptible power supply is used inindustrial production. During charging,the main issue is super capacitor charging control technology. In order to solve theproblem that the equivalent resistance of super capacity of uninterruptible power supply affects the charging efficiency,buckcharging circuit is designed in this paper. The relationship between input and output voltages under different circumstancesis derived. The circuit and charging model is established. Finally the quantitative comparison control mode was verified. Thesimulation based on the model is established in Proteus and the charging current curve is observed through analogue chart,which verified the advantages of quantitative comparison control mode in the charging speed and efficiency.
