摘要： A controlling method of a battery mode of a UPS for an active PFC power supply has the following acts of monitoring the AC power source and determining whether the AC power source is terminated or not, wherein if a determining result is positive, the controlling method proceeds to next act, and switching to the battery mode and converting a DC power source of a battery to a square wave. The square wave has a period, and each half of the period is alternately constituted by at least two ON times and at least two OFF times, and each of the at least two OFF times is equal to or less than a hold-up time of the active PFC load having a hold-up time circuit. Therefore, the voltage of the bulk capacitor of the active PFC power supply under a discharge condition is not lower than the low threshold voltage, since the OFF time of the square wave signal will be kept equal to or less than the hold-up time.

摘要： A control method of an uninterruptible power supply (UPS) for extending a discharge time under a no-load condition instructs a battery of the UPS to discharge by repeating an alternate on and off cycle when the UPS enters a battery mode and after a no-load condition continues over a period of time so that the UPS alternately and repeatedly discharges and stops discharging based on the alternate on and off cycle, and detects if the no-load condition is not present during the discharging period. If not present, the battery is restored to continuously discharge. Additionally, the discharge voltage can be reduced during the discharging period to alleviate the power discharged under the no-load condition. Accordingly, the control method can reduce to discharge under the no-load condition and further extend a discharge time under a no-load condition.

摘要： A power-saving line interactive UPS has a power switch set, a low-frequency transformer, a full-bridge circuit, a main controller, a charge and discharge mode controller, a rechargeable battery and a high-frequency charging circuit. The high-frequency circuit is connected between an AC power input terminal and the rechargeable battery to convert the AC power into a DC power and charge the rechargeable battery. Therefore, when the AC power is normally supplied and the power capacity of the rechargeable battery is not full, the high-frequency charging circuit is activated to charge the rechargeable battery without charging the rechargeable battery through the low-frequency transformer and the full-bridge switching circuit, thereby effectively reducing overall power consumption.
