In order to prevent the losses caused by production equipment downtime,uninterruptible power supply is used in industrial production. During charging,the main issue is super capacitor charging control technology. In order to solve the problem that the equivalent resistance of super capacity of uninterruptible power supply affects the charging efficiency ,buck charging circuit is designed in this paper. The relationship between input and output voltages under different circumstances is derived. The circuit and charging model is established. Finally the quantitative comparison control mode was verified. The simulation 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 .
