We’ve all heard of UPS, otherwise known as Uninterruptable Power Supply. But for the layman – how does it actually work? Furthermore, there are numerous different types of UPS systems – each sporting a different and unique design.
How UPS works
The concept of how UPS works is quite clear, actually.
UPS is the means of using a device to connect the source of power and an electrical device (such as your PC).
The main idea is to ensure an ongoing supply of power is directed to a computer or other electrical appliance when the lights go out, and if there are dips or spikes in power from the grid, your PC (and other electrical devices), will be protected from being damaged.
UPS devices run off batteries to keep your devices up and running, ensuring there is no down-time at all.
UPS Systems should never be confused with generators, which are on standby should the power got out – the function of the generator is not to protect your devices from damage.
Your UPS will ensure that your power is switched over, safely, to battery-operated power, when there are dips and spikes, brownouts or blackouts in the power from the grid. UPS Systems can also be useful in guarding your devices from line noise.
The three components that your UPS is made up of include:
Rectifier – The rectifier stores power in the battery after converting the AC power into DC.
Inverter – The inverter converts DC power into AC.
Battery – The battery’s main function is to store the power to use when the utility is interrupted.
