The first difference between On-Line UPS and LINE INTERACTIVE system is that the battery charger has been exchange with the "Rectifier / Charger" section. The "rectifier / charger" section may consist of two separate parts or a full power block. When main power is on, this part charges the battery and supply inverters energy with a constant DC voltage. If the main power is cut, charger turns off and battery supplies inverter`s DC energy, and from this time on, the battery is getting loose. This type of UPS that known as the Double Conversion UPS, provides the highest protection since the load is always fed with a regulated voltage. In other words, even though main power is on, the charger rectifier and the section Inverter is in active mode. regularly, load that receives its energy,it would well protected against electric power disturbances. Rectifier and inverter thwart transmission line noise and transient voltage swing and provide a stable output voltage. If the input voltage exceeds the permitted range (eg, +10% to -20% ), or completely cut off, the inverter keeps on operating by using battery power.
