fig 4 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/14a.
7. Battery: Sealed lead acid Battery.
