摘要
本文设计一款中小功率投切无冲击不间断电源。整体设计采用"交-直-交"的形式,直流电由市电整流或者蓄电池升压得到,再经过升压和逆变送出。投切过程利用两种直流供电方式上的电压差,用二极管实现,投切过程不会产生任何的相位差和瞬时断电现象,且不需要软件和检测电路参与,具有可靠性高、交流侧电压波动小、无冲击的特点。
The design for the normal operation of load in a period of time when the electricity suddenly interrupted. The whole design used ＂AC-DC-AC＂ form. The direct current can be obtained by the electricity after the rectifier or the battery voltage after boosting and then sent out after boosting and inverter. The cutting process can be realized by diode using voltage differences between the two DC power supply modes. The cutting process will not produce any phenomenon of phase differences and the instantaneous power outages and will not need the involvement of software and detection circuit. The cutting process has highly reliability, lower fluctuation of the AC voltage and surge-free.
