する小型無停電電源器。 In a power supply device for a small computer system, such as a personal computer system, it outputs normally when there is no commercial AC power outage, and
The first winding of a single transformer is used as the primary winding, and the second winding is used as the secondary winding. After that, it is converted from AC to DC, and then the battery is charged. In the event of a power outage, a power outage detection circuit detects the power outage. detecting and converting the direct current of the battery into alternating current via an inverter, making the third winding of the transformer a primary winding, outputting the first winding as a secondary winding, and the alarm circuit. A small uninterruptible power supply comprising a reference voltage circuit, a battery voltage detection circuit, an oscillation circuit, and a two-color LED.
