MAJOR COMPONENTS
Transient Voltage Surge Suppression (TVSS) & EMI/RFI Filters
These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio frequency interference (RFI). They minimize any surges or interference present in the utility line and keep sensitive equipment protected.
Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/PFC circuit converts utility AC power to regulated DC power for use by the inverter while ensuring that the waveshape of the input current used by the UPS is near ideal. Extracting this sinewave input current achieves two objectives: the utility power is used as efficiently as possible by the UPS, and the amount of distortion reflected on the utility is reduced. This results in cleaner power being available to other devices in the building not being protected by the
Inverter
In normal operation, the inverter utilizes the DC output of the power factor correction circuit and “inverts” it into precise, regulated sinewave AC power. When utility power fails, the inverter takes power from the battery through the DC to DC converter and inverts it into alternating current. In both modes of operation, the UPS inverter is
Battery Charger
The battery charger utilizes utility power and precisely regulates it to continuously “float” charge the battery system.
DC to DC Converter
The DC to DC converter utilizes energy from the battery system and raises the DC voltage to the optimum operating voltage for the inverter. This allows the inverter to operate continu- ously at its optimum efficiency and voltage, thus increasing reliability.
