Line Interactive

Standby

Line Interactive Topology can be best explained using the analogy of a tandem bicycle which has 2 sets of pedals to drive the rear wheel. Line interactive operates similarly where two independent power sources share the workload, by sensing the incoming mains voltage and where this is irregular, the two power sources can take over the power output completely, or in the case of a voltage dip or surge, either buck or boost the voltage up or down, to provide a regulated voltage output.

In this type of system, the battery charger, inverter and source selection switch are usually replaced by a single Inverter/DC converter component. This Inverter/DC converter charges the battery, and also converts DC current back to regulated AC for voltage output to connected loads.

AC line power is still the primary power source, with the battery acting as the secondary. When the line power is active, the AC is filtered through to the load whilst the Inverter/DC converter charges the battery. When the power fails, the unit senses the change, brings in the DC, and then operates in reverse.

The inverter/DC converter regulates the output voltage through a Buck/Boost regulator which can supply additional power during voltage sags/brownouts. The main advantage of Line Interactive systems is that the inverter/DC converter unit is always present at the output, which gives a very fast response time to a power failure.

The line-interactive UPS provides a far superior level of protection over the Standby UPS equipment, although does not provide the isolation, regulation and “”no break” output as is provided by an Online UPS.
