On-line interactive UPS, also known as interactive UPS, is a UPS device between the backup UPS and on-line UPS working modes.
According to the working principle of UPS uninterruptible power supply, there are backup UPS, online UPS, and online interactive UPS. There is no conversion time for online UPS, and there is conversion time for online interactive UPS power. This is the biggest difference.
On-line UPS means that no matter whether the grid voltage is normal or not, the AC voltage used by the load must pass through the inverter circuit, and the inverter is always in working condition.
Online interactive UPS means that when the mains power is normal, the inverter of the UPS is in reverse operation (that is, the rectifier working state) to charge the battery pack; when the mains power is abnormal, the inverter immediately turns to the inverter working state, It converts the battery power into AC output, so the online interactive UPS also has conversion time.
The circuit is simple and the cost is low. High reliability. High efficiency, efficiency can reach more than 95%. The overload capacity is strong, and the overload capacity can reach 200% when the utility power is supplied.

The waveform distortion coefficient of the sine wave output by the online UPS is the smallest, generally less than 3%; the online UPS generally uses PWM technology above 20kHz, and its noise is relatively small, about 50dB.(commercial Offline UPS system)
Since the online UPS is powered by the UPS inverter when the mains power is normal or when the mains power is interrupted and the battery is supplied to the inverter, the power supply to the load is provided by the UPS inverter; when the mains power is interrupted, the online UPS The power supply can truly realize uninterrupted power supply to the load.
