Abstract
An uninterruptable power supply system including a battery, a converting module, a charging circuit, a first switch, a power detecting circuit and a controlling module is provided. The converting module is coupled between a power inputting terminal and the battery, and connects to a load. The power inputting terminal is connected to a power. The battery is charged through the converting module or discharges to the load through the converting module. The charging circuit is coupled between the power inputting terminal and the battery for charging to the battery. The first switch is coupled between the charging circuit and the battery. The power detecting circuit is coupled to the battery for detecting a power value of the battery. The controlling module is coupled to the power detecting circuit, and control the ON/OFF state of the first switch for making the battery be charged or discharge according the power value or power supply state of the power.
