Main use:

Line-interactive UPSs are the most common uninterruptible power supplies for small businesses, for protecting web servers and corporate department servers. The direct/alternating current converter, i.e. the inverter, is constantly connected to the output. By operating the inverter in reverse mode, the battery is charged from the mains supply. When the incoming power is lost, the switch opens and the UPS output receives power from the battery. Since the inverter operates continuously and is connected to the output, these systems provide better filtering compared to standby UPSs and work with shorter switching transients. In line-interactive units, there is usually a voltage regulating transformer in addition to all this. This provides additional voltage regulation by adjusting the transformer taps depending on changes in the input voltage. Voltage regulation is an important function under low voltage conditions, without which the UPS would have to switch to battery power and then switch off the consumers in the long term. More frequent battery use leads to premature battery wear. The advantages of such uninterruptible power supplies are high efficiency, small size, low cost and high reliability.
