Upon restoration of utility AC power, after a utility AC power outage and prior to a UPS
automatic end-of-discharge shutdown, the rectifier/charger shall automatically restart,
walk-in and gradually assume the inverter and battery recharge loads.
15.2.1.5.
Battery Recharge
In addition to supplying power for the inverter load, the rectifier/charger shall be capable
of producing battery charging current sufficient to replace 95% of the battery discharge
power within ten (10) times the discharge time. After the battery is recharged, the
rectifier/charger shall maintain the battery at full charge until the next emergency
operation.
15.2.1.6.
Overvoltage Protection
There shall be DC overvoltage protection so that if the DC voltage rises to the preset
limit, the UPS will shut down automatically and initiate an uninterrupted load transfer to
the static bypass line.
15.2.2. Inverter
15.2.2.1.
General
The term inverter shall denote the equipment and controls to convert DC from the
rectifier/charger or battery to precise AC to power the load. The inverter shall be solidstate, capable of providing rated output power, and for increased performance the inverter
shall be a pulse-width-modulated design and utilize insulated gate bipolar transistors
(IGBTs).

Fault Clearing and Current Limit
The inverter shall be capable of supplying an overload current of 150% of its full-load
rating for one minute. For greater currents or longer time duration, the inverter shall have
electronic current-limiting protection to prevent damage to components. The critical load
will be transferred to the static bypass automatically and uninterrupted. The inverter shall
be self-protecting against any magnitude of connected output overload. Inverter control
logic shall sense and disconnect the inverter from the critical AC load without the
requirement to clear protective fuses.

within 5% and the phase displacement is to be 120 degrees within a range of ±1.5
degrees.
15.2.2.7.
Inverter Shutdown
For rapid removal of the inverter from the critical load, the inverter control electronics
shall instantaneously turn off the inverter transistors. Simultaneously, the static transfer
switch shall be turned on to maintain continuous power to the critical load.
