  • Page 6 The SPS generates DC power supply needed by operation of the circuit of the UPS itself. The Bypass provides a path that utility can power the output directly when the Inverter is not executed. Maintenance Bypass provides another path that utility can power the output directly when UPS is in maintenance status.

    4. Working Principle of the Major Functional Block 4.1 Switch Power Supply The Switch Power Supply (SPS) supplies DC power for UPS operation. The input source of the SPS is the battery, or the output of the charger. SPS_BUS+ R LINE +12V Output S LINE Battery...
  • Page 8 4.2 PFC/Booster BUS+ Battery R/S/T BUS- Figure 4.2 PFC/Booster As shown in the Figure 4.2, when Q1/Q2 is on and D1/D2 is off, the current will increase to store energy in choke(L1/L2). When the Q1/Q2 is off and D1/D2 is on, the choke will release energy. Therefore, we can control the current in chokes (input current) by regulating the time of Q1/Q2 on and off.

    4.4 Charger The function of charger is to charge and maintain the batteries at fully charged condition. The charger charges the batteries with a constant current at initial stage. At the same time, the battery voltage keeps increasing until reaching the constant charge voltage point. Then, the charge current will decrease accordingly, now it’s in second stage.
