並且，交替的對正半周電壓VP與負半周電壓VN進行昇壓 與功因修正，並且轉換輸出成一第一輸出電壓Vol與第二 輸出電壓Vo2。二組昇壓轉換器（10、12)分別交替的將第 一輸出電壓Vol與第二輸出電壓Vo2送至換流器16,同時， 換流器16將第一輸出電壓Vol與第二輸出電壓Vo2換流成 一交流電Vac輸出。 復參考第一圖。雙昇壓型不斷電供電裝置1工作在市 電供電模式時，其所使用的備援電池11無法從線路中進行 充電，並且，備援電池11在長時間的閒置下，通常會導致 内部電力消耗殆盡。由於雙昇壓型不斷電供電裝置1本身 的線路並無提供充電器，所以，需要充電的備援電池11必 須從外部充電器才能得到充電。如此，習用之雙昇壓型不 斷電供電裝置1常需要額外設計獨立的充電器模組（未標示） 對備援電池11進行充電而導致成本的上升和使用上的不方

New description: [New technical field] A constant power supply device, especially an uninterruptible power supply device that charges the backup battery while the utility power is supplied. [Prior Art] A conventional dual boost type uninterruptible power supply device 1, as shown in the first figure, uses two sets of boost converters (10, 丨2) for boosting and powering in the mains power supply mode. Due to the correction, the two sets of boost converters (12, 12) receive a positive half cycle voltage VP and a negative half cycle voltage VN from the rectifying unit 14, respectively, and the alternating positive half cycle voltage VP and the negative half cycle voltage VN rise. The voltage and the power factor are corrected, and the output is converted into a first output voltage Vol and a second output voltage Vo2. The two sets of boost converters (10, 12) alternately send the first output voltage Vol and the second output voltage Vo2 to the inverter 16, respectively, while the inverter 16 sets the first output voltage Vol and the second output voltage. Vo2 is commutated into an AC Vac output. Refer to the first figure. When the double boost type uninterruptible power supply device 1 operates in the mains power supply mode, the backup battery 11 used therein cannot be charged from the line, and the backup battery 11 usually causes internal power after being left idle for a long time. Run out. Since the charger of the double boost type uninterruptible power supply device 1 itself does not provide a charger, the backup battery 11 that needs to be charged must be charged from an external charger. Thus, the conventional dual-boost type uninterruptible power supply device 1 often requires an additional design of a separate charger module (not shown) to charge the backup battery 11 to cause cost increase and inconvenience in use, and also This will result in an increase in the number of failure points of the product.

The commutation unit is coupled to the first boosting unit and the second boosting unit to receive the first voltage and the second voltage, and to output an AC output electric dust. The main difference between the uninterruptible power supply device of the second embodiment of the present invention and the first embodiment is that the charging circuit in the uninterruptible power supply device of the second embodiment is coupled to the rectifying unit, the backup battery, and the first boosting device. The unit controls the first boosting unit to store an alternate operation of charging power and charging power to charge the backup battery. The main difference between the uninterruptible power supply device of the third embodiment of the present invention and the first embodiment is that the charging circuit in the uninterruptible power supply device of the third embodiment is coupled to the rectifying unit, the backup battery, and the first liter.
