Recently, the need for sensitive equipment has grown considerably in the house, but the availability is declining. For this reason, companies have started, with backup generators as a source of backup power. This can lead to fights, including how it is connected directly to the generator to a load that is too sensitive. To counter this, these questions of a UPS system to be installed, even if further problems can be accommodated by this through a combination ofUPS and generator. These problems can be sorted by inserting the appropriate UPS.
There are some sources that can go wrong with this configuration, but this can be resolved. The first main problem is that the UPS inverter problems with their ability to be synchronized with a frequency of unstable, this can lead to further problems, especially when you consider that the generators of course, have difficulty in controlling the frequency. This can lead to a "can not synchronize to bypass"Alarm system. There is an even higher frequency and voltage stability to synchronize the demand on the generator, as it is to circumvent the effective load transfer.
The UPS is essential for protection against short power outages of the network. However, the battery can prevent some forms of control, it is because the control circuit power can cause problems with feeding. You can also click on an input current unstable, which can draw one of the causes of the generationQuality problems, such as the THD (Total Harmonic Distortion) is known. Some systems can be up to 30% THDi, so the excessive heat. Generators standby power voltage and frequency problems can also occur if the entire load of the UPS is immediately applied to the generator.
Transformerless devices can now integrate solutions to all these problems. To improve the compatibility of frequency changes without input from alarm generators unstable UPS, the generator should be 'the' contractbe used. This function disconnects the load from the UPS-frequency generator, and causes the system to follow its internal frequency, thus eliminating the problem of fluctuating frequencies that may occur.
The generator of waiting, this technique is suitable to produce a THDi less than 7%, has a separate battery charger circuit, together with a signal 'on'. All this reduces the charge current of the UPS battery, and reduces ultimately, heatingCharacteristics of the generator. This new technology is limited only Renaissance step loading throughout the Web, enabling the rectifier in a configuration file. In addition, UPS systems are designed to eliminate unnecessary to increase the excitement and enthusiasm.
