Description

不斷電系統用的升壓模組Boost module for uninterruptible power system

本發明是有關一種不斷電系統用的升壓模組，尤其是可有效簡化電路的不斷電系統用的升壓模組。The invention relates to a boosting module for an uninterruptible power system, in particular to a boosting module for effectively simplifying a circuit of an uninterruptible power system.

在不斷電系統(UPS)中，因為電池的蓄電提供了可靠的電能量，保證了不間斷系統能夠穩定的運行。以往的不斷電系統(UPS)大都是使用鉛酸電池，並透過推挽式轉換器(Push-Pull)將電池的電壓提升，再將提升的電壓輸出至逆變器(inverter)。In the uninterruptible power system (UPS), because the battery's storage provides reliable electrical energy, the uninterrupted system can operate stably. In the past, the uninterruptible power system (UPS) mostly used a lead-acid battery, and the voltage of the battery was boosted by a push-pull converter (Push-Pull), and the boosted voltage was output to an inverter.

The UPS must also add extra volume to match the circuit with the push-pull converter. The setting, and the battery output voltage through the push-pull converter, will cause the voltage output efficiency to drop.

因此，如何設計出一種不需透過推挽式轉換器，即可直接將電池的電壓輸出，令電路得以簡化，整體系統的體積獲得縮減，並提高電池的電壓輸出效率，都會是本案所要著重的問題與焦點。Therefore, how to design a voltage output of the battery without using a push-pull converter can simplify the circuit, reduce the volume of the overall system, and improve the voltage output efficiency of the battery, which will be emphasized in this case.
