| 摘要 | An uninterruptible power supply device is basically a device that performs a full-time inverter feeding system using a first semiconductor switch, and when a second semiconductor switch, which is an optional item, is connected in parallel to the first semiconductor switch and a full-time bypass feeding system is selected, serves as a device that performs the full-time bypass feeding system using the second semiconductor switch. This leads to a low device cost compared with the case in which an uninterruptible power supply device employing the full-time inverter feeding system and an uninterruptible power supply device employing the full-time feeding system are designed and manufactured separately. | ||||||
