UPS Technology and Operation
What is a UPS?
UPS is the abbreviation for Uninterruptible Power Supply. In very simply terms a UPS is a power conditioner with a battery. The battery makes it possible to offer protection against power failure / black outs.
Generally there are two types of systems available in the market today – Offline / Standby and Online
A UPS will consist of three key elements:-
- Rectifier / Charger– takes the incoming AC supply and converts it to DC to trickle charge the DC battery and where applicable feed the inverter.
- Battery– to store the DC energy delivered from the rectifier/charger
- Inverter– converts DC from the battery to a regulated AC voltage to feed the critical load.
