The UPS is uninterrupted power supply equipment. It contains the following
1. Rectifier - It will conver the AC power to DC
2. Battery Bank – It will store the charge and deliver the power to the inverter
3. DC - DC Converter – It will increase the DC voltage ( Like DC Booster)
4. Inverter - It will convert the DC Power to AC power and feed to the load
5. Static by pass switch – Incase any problem in the above it will divert the power from mains power supply to load
6. Manual by pass switch – It will use to take any maintenance or replacement of any modules / PCBs
5. Transient voltage and surge supression filter circuit – It will filter the unwanted surge / Harmonics.
