Fig 5 UPS Principle Diagram
1. Input filter: Complete filtering the input AC utility power to provide the clean power for UPS.
2. AC/DC converter: Convert the filtered AC mains to DC and boost the DC for DC/AC inverter.
3. DC/DC booster: When the UPS works in battery mode, the circuit boosts the DC for DC/AC inverter.
4. DC/AC inverter: Convert the boosted DC to stable AC output.
5. Bypass: When overload or failure of inverting happen in the UPS, it transfers to bypass mode to supply power
to loads.
6. Charger: Standard unit provides 1A; long backup unit provides 7A.
7. Battery: Sealed Lead Acid Battery.
8. Output filter: Complete filtering the output of the UPS to provide the clean power for loads.
