Abstract

See full text

This uninterruptible power supply device is basically a device (1) that executes a constant inverter power supply system using a first semiconductor switch (3), and in the cases where a second semiconductor switch (20), i.e., an option item, is connected in parallel to the first semiconductor switch (3), and the constant bypass power supply system is selected, the uninterruptible power supply device serves as a device (1A) that executes the constant bypass power supply system using a second semiconductor switch (20). Consequently, compared with the cases where an uninterruptible power supply device employing the constant inverter power supply system, and an uninterruptible power supply device employing the constant bypass power supply system are separately designed and manufactured, cost of the device can be reduced.
