At the heart of the UPS is the rectifier, which converts AC power from the main power supply into DC power to charge the battery. The battery serves as a backup power source and is typically rechargeable. During normal operation, the rectifier charges the battery while providing power to connected devices.
A UPS consists of three main components: the battery, the rectifier, and the inverter. The battery is responsible for storing electrical energy and providing power when the main power source is lost.
