The Difference Between The Inverter And The UPS.
Feb 19, 2018

An inverter is an electric current conversion device that converts direct current to alternating current or alternating current to direct current.

UPS is an uninterrupted power supply device, the principle is the battery + inverter, mains by inverter is converted to direct current, direct current to the battery charging, if mains power, immediately converted to battery through the inverter can be converted into alternating current (ac), available for electrical appliances use directly.

There is also a word "stabilizer" stabilizer, which can be used to maintain a stable voltage at a fixed voltage, which is good for the normal use of electrical appliances.

In civil use, regulators use a wide range of regulators, such as refrigerators and air conditioners, and many users add high-power regulators to the overall line, thus protecting all electrical appliances. We know that in particular, when the power failure is restored, the voltage will have an overload peak and the instantaneous voltage is too high, which is why most electrical appliances are damaged.

UPS power supply is suitable for the unexpected power outage may cause data loss, such as computer electronics, such as electrical appliances generally 1 second of power outage will start data loss caused by the UPS is not indirect power supply may be used for protection, such as server, mobile unicom signal towers, etc.

Some of the less demanding devices also use backup power systems, such as emergency exits, which are slightly slower, with a backup engine for more than a dozen seconds, and batteries. For example, the power plant's own electricity system is equipped with a backup diesel unit worth millions of dollars, which is preheated all day long. If there is an unexpected power failure, the power supply will be restored in a dozen or tens of seconds.

But the inverter switching device, because it is just a current rarely used alone, a typical example is the car power, is an inverter, it from the car cigarette lighter 12 VDC, convert alternating current (ac), 220 for the use of ac electric appliance, such as a laptop
