Where it is used
A UPS is an uninterruptible supply with its own energy storage. It feeds equipment that cannot ride through a mains break.
The core is a rectifier-charger that makes DC from AC, and an inverter that makes AC from DC again. While mains is present, the battery sits at its normal charge voltage.
When mains drops, the battery feeds the inverter immediately so the AC output continues.
