Another important issue is reliability. The prime aim of a UPS is to protect your
load. Therefore, the UPS should be much more reliable than the AC source. An
unreliable UPS may suffer the problem of frequent break down, even more frequent
than AC failure, and the cost of repair may become more than the cost of the unit
itself.
Generally, there are four different modes of operation, the NORMAL OPERATION
MODE, the BACK-UP (BATTERY) MODE, the RESERVE MODE and the
MAINTENANCE BYPASS MODE. These are explained below.
Normal Operation Mode:
The rectifier converts the AC input to DC power to supply the inverter and charge the
batteries simultaneously. All the fluctuations, surges and spikes of the AC input are
removed during AC to DC conversion. Therefore the AC supplied by the inverter is
clean and stable.
