UPS power supply working principle

What is the working principle of the UPS power supply?

Answer:

Backup type backup working principleThe backup is also called non line uninterruptible power supply (Off-Line UPS), it is only "backup" nature of the UPS, the city electricity direct power supply for the electric device for battery charging (Normal Mode), once the city electric power quality instability or power outage, electric circuit will automatically cut off the power, DC power the pool is converted into AC power over the task (Battery Mode), until the city returned to normal, "UPS only in the power cut will intervene power", but from the AC DC power supply is Fang Bo, only to capacitive load, such as computer and monitor.
To provide a stable voltage as CPU, in the total power supply voltage instability, CPU power will automatically power off to ensure the normal work of CPU of new start based on the control board, or choose a good power supply, CPU power supply is secondary, the motherboard can analyze the risk value of CPU,
The UPS power supply is to supply the standard voltage of the inverter to the output voltage of the inverter after the rectifier is filtered. The electric energy in the battery is inverted to the standard voltage by the inverter to supply the load to ensure the supply of green, stable and continuous power supply.
On line staggered online interactive working principleLine interleaving also known as online interactive or online interactive (Line-Interactive UPS), the basic mode of operation and off-line, the difference is that online is not interleaved on-line in the whole power supply, but all the time in the power supply condition monitoring of city electricity, has boost and decompression compensation circuit in the power supply situation, real-time correction electricity is not ideal, and reduce unnecessary "Battery Mode" switch to extend battery life.
Online online UPS (On-Line UPS) mode of operation for electric and electric equipment is isolated, electricity will not direct power supply for the electric equipment, but the UPS is converted into DC, then diverge, a way to charge the battery, another way to alternating current. The power supply for the electric equipment, electric power quality instability or power outage, the battery from charging into electric power supply, until the city returned to normal only to charge, "UPS is involved in the entire process in the whole process of electricity". The utility model has the advantages of output wave and electricity for the same is pure sine wave, and no noise, no influence electrical instability, can supply power to the "inductive load", such as the electric fan, as long as the premise UPS enough output power, can supply power to any use of electricity equipment.
