5.1. UPS System Block Diagram

Fig 5.1

Figure 5.1 above illustrates the True On-Line
Double Conversion architecture of the UPS
system. The major modules consist of:

1. An AC to DC power converter (Rectifier) with

PFC control circuit

2. A DC to AC power high frequency inverter
3. An Intelligent Battery Charger
4. A bank of stationary maintenance-free

batteries

5. A DC to DC push/pull converter control

circuit

6. A Static Bypass Loop
7. Input & Output EMI Filter

The table below provide a summery guide to
the UPS operating modes against the Utility AC
Power Source conditions.

Paragraph 5.2 ~ 5.7 below provide detailed de-
scriptions of the UPS operating principle.

5.2. When Mains is Available

When Mains is available, the AC source is rec-
tified  to  DC,  partially  fed  into  the  charger  to
charge  battery  and  partially  fed  into  inverter.
The  inverter  revert  the  DC  to  a  cleaned  and
pure  AC  to  supply  energy  to  the  load  con-
nected. The
