Typical current and voltage control loops for UPS inverter. In SPWM control technique, the output voltage feedback is compared with a sine reference signal, and the error voltage is compensated by a PI regulator to produce the current reference. The current through the inductor or the capacitor is sensed and compared with the reference signal.
Generally, the tasks of output voltage control for UPS inverters are providing fast dynamic responses and maintaining a perfect sinuso-idal voltage waveform even with nonlinear or changing loads. To achieve these aims, many controllers have been proposed in the literature.
It is well known that the main control objective in an UPS inverter is the tracking of the delivered voltage towards a desired sinusoidal reference in spite of the presence of distorted loads, . UPS systems can be classified as static, rotary and hybrid.
It consists of an AC/DC converter, a battery bank, a DC/AC inverter, and a static switch. A passive low-pass filter may also be used at the output of the UPS or inverter to remove the switching frequency from the output voltage. The static switch is on during the normal mode of operation.

What it is: When you notice that your UPS isn't working after a power outage, the first troubleshooting step you should take is to check its incoming power supply. Remember: the UPS will drain its battery during a power outage. If the outage goes on for too long, the UPS will lose all its power and must recharge when power is restored.
Ageing Power Supplies If your system regularly overheats, an ageing power supply can cause your UPS to fail. But troubleshooting an outdated power supply isn't as simple as other UPS problems. You need someone on call 24/7 to get you back up and running as quickly as possible.
When that happens, the UPS will not work after the power cut. How to fix it: One way to solve this issue is to disconnect the UPS from its wall socket and leave it alone for a few minutes. You can plug the UPS back into the wall socket when you're confident that the power cut is over and your power supply has become stable.
