Rectifier : this part of the UPS charging current for the battery and also the supply requirements for the inverter and can converts the incoming alternating current (ac) supply to direct current (dc).
Charger : in a number of UPS systems because of the nature of these design another battery charger is applied, this is very common on small sub 3kVA models and is more common on sub 60kVA UPS systems.
Battery : this is actually the power storage section and is kept charged possibly by the rectifier or even a separate charger. As AH (ampere hour), which will be how many amperes of current that the battery can supply for an hour, their storage capacity is generally exhibited. There will be an amount of limiting facets based upon the application, usually if the design calls for a short autonomy (amount of time the battery will support its load for), the batteries can be cleared to a degree, in the case of emergency lighting where there's a requirement for a autonomy the battery won't be permitted to discharge so much. These problems help allow the optimum design life of the battery to be achieved.
Inverter : an ac output is provided by this section of the Uninterruptible power supply to the load that is in phase with the insight mains supply. Due to the amount of conversions (ac to dc to ac) and the filter involved it could be referred to as a 'clean supply.'
Static Switch : this signal can be as simple as an exchange or even more generally using thyristors, its function would be to switch the load between the inverter and the utility mains supply. So that any switching between the two will be virtually seamless as has been earlier mentioned the output of the inverter is in phase with the utility mains source. This design means that if the inverter activities an overload condition, because fast over-current diagnosis tracks it will shift the load to the more sturdy mains supply. A normal example would be when a server sheet is switched on, the inrush current, depending upon the size of one's uninterruptible power supplies, could cause the transfer to the power mains offer, and once switched on the load can transfer back to the inverter providing the inverter has sufficient capacity to support the load. Also a fault on the inverter can cause the load to be moved, again essentially seamlessly; it'd be unusual for any loss in load to happen during these circumstances.
Preservation Bypass : more generally present in UPS systems with a capacity of 6kVA or greater. This design allows force to be transferred under controlled conditions to the utility mains and the UPS to be turn off without loss. Generally completed for program UPS preservation or UPS fix.
External Maintenance Bypass : the installing of an maintenance bypass can allow the UPS to be removed/replaced without disturbance to the load, also, if the actual maintenance bypass is given from a separate supply it can allow load screening in the case of a major UPS restoration and/or checking of the autonomy under simulated load problems while the site load has been supported by the external maintenance bypass circuit. When letting the UPS System to be bypassed onto standby diesel generator power this is used. Instead, when batteries are removed and replaced, it may only be done by setting the uniterruptible power supply into outside bypass.
