    On-line UPS: Regardless of the grid voltage is normal or not, the AC voltage used by the load must pass through the inverter circuit, the inverter has been in working condition. So when the power cut off, UPS can immediately provide its store energy through the inverter into AC power supply to the load, In order to achieve the  zero switching of output voltage. Online UPS is suitable for the ...
