and charger use the IGBT with a self-extinguishing function and a high switching speed.
On the output there is an isolation transformer for extra power conditioning.
4.2 Modes of Operation
4.2.1 Emergency (Battery Backup)
In the event the AC power from the utility system fails, the DC power is supplied from
the batteries to the chopper and to the inverter to provide a continued and stable AC
power supply to the load without interruption.
4.2.2 Normal (Inverter)
The rectifier converts AC to DC to power the inverter, which supplies
power to the critical load and simultaneously float charging the batteries.
4.2.3 Battery Charge
The charger will float charge the batteries while no load is being powered by normal
mode.
4.2.4 Static Bypass
If the UPS unit is in severely overloaded or develops an internal fault, power is
automatically switched from the units main circuit to the bypass circuit. Power is
conditioned by line filters, and the isolation transformer during static bypass operation.
