摘要： A failure-free power source device memorizes the history of errors of a commercially available power source, monitors the stability of the power source on the basis of the history, directly outputs, when the power source remains stable for more than a predetermined period of time, an AC input as an AC output, and releases, when an error occurs in the power source, energy stored in an accumulator until a predetermined period of time expires to thereby output it as an AC output via an inverter.
