Figure 6-2. Path of Current Through the UPS in Online Mode

The inverter produces a three-phase AC output to a customer's load without the use of a transformer. The
inverter derives regulated DC from the rectifier and uses IGBT devices and pulse-width modulation (PWM) to
produce a regulated and filtered AC output. The AC output of the inverter is delivered to the system output
through the output contactor K3.

If the utility AC power is interrupted or is out of specification, the UPS automatically switches to Battery mode

to support the critical load without interruption. When utility power returns, the UPS returns to Online mode.

If the UPS becomes overloaded or unavailable, the UPS switches to Bypass mode. The UPS automatically
returns to Online mode when the overload condition is cleared and system operation is restored within
specified limits.

If the UPS suffers an internal failure, it switches automatically to Bypass mode and remains in that mode until
the failure is corrected and the UPS is back in service.

6.2.3

Energy Saver System Mode

When the UPS is operating in ESS mode, the bypass source supplies the commercial AC power to the load
directly through the static switch. Some power line filtering and spike protection is provided to the load but no
active power conditioning or battery support is available. All power converters are off and are in the ready state
(in case a forward transfer is needed). During this mode, the output contactor is closed and the link is
maintained through the diode bridge.

If commercial power voltage or frequency disturbances are detected, the system forward transfers to Battery
mode for minor disturbances and then to double-conversion mode for more severe disturbances. During a
complete power outage, the transfer takes place within 2 ms to ensure loads being fed by the system output
are not interrupted. All forward transfers transfer to Battery mode before returning to double-conversion mode.
