SYSTEM OVERVIEW
1.1. Construction of the UPS
General Topology
：
The UPS system is composed of input breakers, input filter & protection network,
rectifier, battery bank, inverter, static switch, bypass breaker, isolation transformer
and output filter. The basic topology is shown in the diagram above. Under normal AC
mode, energy from the AC source is converted to DC power and supplied to the
inverter to charge the batteries to its full capacity all the time, ready to support the
output load in case of AC source failure.
Although the principle and operation of a UPS seems simple and straightforward, the
requirement for a reliable and intelligent UPS makes the design and manufacturing of
a high power UPS one requiring advanced technology, intelligence, experience and
most important, consideration of the user interface. Many years have been spent in
designing the most rugged, intelligent and reliable UPS for the market, and a safe and
convenient UPS for the user.
Choosing the best and most suitable UPS for a given application can be easy or
difficult, depending on the client’s knowledge of key parameters. The most obvious
specification, output power, depends on the size of the load. Often, an allowance of
50% more power is added to the present load requirement, both for tolerance and for
future expansion.
