They serve two main functions: converting AC to DC for load supply after filtering, and providing charging voltage to the battery.
How does a ups work?
Working Principle: When the main power supply is available, the UPS passes the incoming AC power through the rectifier to charge the battery and simultaneously supplies AC power to the connected equipment. In case of a power outage, or when the voltage fluctuates outside a safe range, the battery takes over and powers the inverter.
How does a ups inverter work?
The inverter, on the other hand, converts DC power from the battery back into AC power to supply the connected devices. When the main power source is present, the UPS continually charges the battery through the rectifier while simultaneously supplying power to the system through the inverter.
What is the difference between a UPS & energy storage?
UPS Definition: A UPS (Uninterruptible Power Supply) is defined as a device that provides immediate power during a main power failure. Energy Storage: UPS systems use batteries, flywheels, or supercapacitors to store energy for use during power interruptions.
