All regulators, have taken advantage of the same technology to achieve stable output voltage. Output voltage dividing resistors connected to the amplifier inverting input Switchgear & Substation terminal of the sampling error, the error amplifier non-inverting input connected to a reference voltage. Always try to force the error amplifier input equal at both ends. To this end, it provides the load current to ensure that the output voltage stability (ie negative feedback).
Regulators pictures regulator and UPS are different concepts, but many of my friends are always wrong to think the regulator is UPS, essentially there is a difference; UPS into line and back-up, general computer equipped belong back-up, and it belongs to an emergency power supply; back-up is an electronic switching regulator with the regulator part, can be used as the regulator Used, but regulators are not effective; regulator: it is against voltage instability designed primarily as a back-end equipment protection purposes, for equipment protection function better. electric energy meter Generally large UPS systems must also be equipped with a bypass regulator that LW-PLG regulator. The above describes the concept of the regulator, UPS is here to talk about what?
UPS in Chinese means "uninterruptible power supply" is the English "Uninterruptible Power Supply" acronym, it can protect the computer system after a power outage to continue working for some time to allow the user to save an emergency, so you do not work due to power failure or loss of influence data. It is in the computer systems and network applications, mainly plays two roles: one for emergency use, to prevent a sudden power failure affecting the normal operation, causing damage to a computer; the second is to eliminate surges on mains, instant high voltage, instantaneous low voltage, wire noise and frequency Air circuit breaker offset and other "power pollution", to improve power quality, providing high-quality power for computer systems.
