Many people think that voltage stabilizers, transformers, and UPS are the same concepts, but in fact, they are different. Taking UPS as an example, many friends always mistakenly think that the voltage stabilizer is the UPS, which is essentially different; UPS is divided into online and backup types. Generally, computers are equipped with backup types, which belong to the emergency power supply. Kind of, voltage stabilizer: It is designed for voltage instability, mainly used for back-end equipment protection, and has a more complete protection function for equipment.
Here is the content list:
l The difference between voltage stabilizer and transformer
l The distinction between voltage stabilizer and UPS
Electricity can produce magnetic fields, and magnetic fields can also be converted into electricity. When one coil is connected to alternating current, an alternating magnetic field will be generated, and then this alternating magnetic field will be passed through another coil, and a voltage will be induced on the other coil. This is the principle of a transformer.
The AC voltage stabilizer uses the principle of negative feedback. There is a circuit in the voltage stabilizer that can detect changes in the output voltage (the voltage divider resistor sampling circuit at the inverting input of the error amplifier can be reduced to only one integrated chip). When the output voltage changes, the circuit that detects the output voltage change is provided by the chip to provide feedback to the private server motor, and then the servo motor drives the rotating arm to automatically adjust the position of the brush to stabilize the output voltage. This is the simplest stable Depressor.
To sum up, the transformer does not have the effect of voltage stabilization, but the use of negative feedback technology can be used to design a voltage stabilizing transformer, this is no problem, but the general transformer is not like this. The output voltage of the transformer does not change much within a certain range of use, which is not a concept with what we call voltage stabilization.
All home voltage stabilizers use the same technology to stabilize the output voltage. The output voltage is sampled by a voltage divider connected to the inverting input of the error amplifier, and the non-inverting input of the error amplifier is connected to a reference voltage. The error amplifier always tries to force the inputs of both ends to be equal. To this end, it provides load current to ensure stable output voltage (that is, negative feedback).
Generally, giant UPS should even be equipped with a regulated bypass system, that is, an LW-PLG regulator. The conception of voltage stabilizer was introduced higher than, what's UPS here?
UPS will make sure that the pc system continues to figure for an amount of your time when an influence outage so that the user will reserve it in an associate emergency so that you'll not be affected or lost because of an influence outage，data. It main plays 2 roles in laptop systems and network applications: one is emergency use, to forestall sudden power outage from touching traditional work and inflicting harm to the computer; the opposite is to eliminate power surges, instant high voltage, and instant power offer on the mains. "Power pollution" like low voltage, wire noise, and frequency deviation will improve power quality and supply high-quality power for laptop systems. In terms of basic application principles, UPS could be a power protection device that contains energy storage devices, uses inverters because of the main elements, and stabilizes voltage and frequency output.
