INTRODUCTION TO UPS

UPS stands for Uninterruptible Power Supply. UPS is used to provide power for a short or long period of time depending on UPS’s capacity to maintain the operation of power equipment and computers in the event of a power failure.

UPS composition consists of the following major components:

• Battery: It’s a power storage facility.
• Charger: performs battery charging.
• Rectifier: Converts alternating current to direct current
• Inverter: Converts direct current into alternating current.

The operating mechanism of each type of UPS is not the same, but all follow the same general principles as follows:

• When the mains power is normal: The battery is charged.
• When there is a problem with the grid: The direct current from the battery will be reversed into alternating current to supply electrical equipment.
