ON VIDEO How to make a simple inverter 2500W, D718


A UPS, also known as an uninterruptible power supply (UPS), provides backup power when your regular power source fails or the voltage drops too low. It allows a computer and connected equipment to be shut down in a safe and orderly manner.

 The size and design of a UPS determines how long it will provide power.

What are the different types of inverters?
Different levels of power protection exist for UPS systems: standby, line interactive, and double conversion.
Sleep mode is the most basic UPS level. A UPS relies on battery backup power in the event of frequent power problems such as a power outage, voltage sag, or power surge. When incoming utility power falls below or exceeds safe voltage thresholds, the inverter switches to DC from the battery and then reverses to AC to run connected equipment.
A line-interactive UPS incorporates technology that allows it to correct minor voltage fluctuations, without switching to the battery. They provide current during events such as a power outage, voltage drop or rise.

A double-conversion UPS provides constant, clean, near-perfect power, regardless of incoming power conditions. This process converts the incoming alternating current into direct current. Uninterruptible power supplies with this technology operate on 100% isolated DC and have zero transfer time because they never need to switch to DC. They are designed in particular to protect critical IT equipment and telecommunications installations against damage caused by power failure, voltage sag, overvoltage, or frequency variation.
