What is the difference between what we usually call switching power and ups?
Switching power supply is a simple power supply, and the transformer power supply name difference. High efficiency and stable operation Wide voltage range.
UPS on the complex it includes switching power supply function is different from the power supply. It consists of step-down circuit boost circuit charging circuit detection circuit and battery. It is widely used in emergency power systems, protection of computer information, security for the security system. Remember the crash in Wenzhou? Power failure caused by automatic monitoring paralyzed, and this time on the use of the UPS.
Use is not the same, the function is more different. Not in the same breath.
Generally speaking, switching power supply and UPS power supply principle and role are different:
1. Switching power supply is the use of modern power electronics technology, control switch opening and closing time ratio, to maintain a stable output voltage of a power supply. (DC-DC); the other is the AC switching power supply (AC-DC). Switching power supply output is generally DC, the role of emphasis on power conversion The
2.UPS is uninterruptible power supply (uninterruptible power system) in English abbreviation, is able to provide a sustained, stable, uninterrupted power supply. The principle is relatively complex, the input and output are AC AC-AC (internal including AC-DC, DC-DC, DC-AC). The role of focusing on maintaining the output power supply stability, while ensuring that the input can still continue to uninterrupted power supply.
