  • Inverter apparatus and method of controlling the same
    Patent number: 10511235
    Abstract: An inverter apparatus includes a first switch, a second switch, a third switch, a fourth switch, a load detection unit, and a control unit. The first switch and the fourth switch form a first switch assembly, and the second switch and the third switch form a second switch assembly. The control unit selects a control mode to be that two switches of the first switch assembly are not turned off and at least one switch of the second switch assembly is turned off, or two switches of the second switch assembly are not turned off and at least one switch of the first switch assembly is turned off, or two switches of the first switch assembly and two switches of the second switch assembly are not turned off.

  • Uninterruptible power system, control apparatus of the same and method of controlling the same
    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.
