  • Patent number: 10333343
    Abstract: An uninterruptible power system includes a power conversion apparatus, a switch unit and a control apparatus. The switch unit outputs a mains voltage in a line mode, and output an alternating conversion voltage in a battery mode. The control apparatus is configured to generate a base triangular wave signal according to the mains voltage. When the uninterruptible power system is in a battery mode and the control apparatus detects the regeneration of the mains voltage, the control apparatus is configured to determine whether a cross-over value of the base triangular wave signal is within a predetermined range when the mains voltage is at a zero-cross point. The control apparatus is configured to control the switch unit to output the mains voltage instead of the alternating conversion voltage when the cross-over value of the base triangular wave signal is within the predetermined range.
