Abstract
A controller of this uninterruptible power supply apparatus performs, while an inverter power feeding mode is being performed, a test mode in which a bypass circuit is brought into conduction and an output current from an inverter is decreased, and it is determined whether or not the bypass circuit operates normally based on an output voltage from the inverter. Therefore, when the bypass circuit does not operate normally, the bypass circuit can be repaired or replaced, to prevent operation of a load from being stopped when a fault occurs in the inverter.
