摘要: An uninterruptible power supply comprising a first switch unit, a charging circuit, a first voltage conversion circuit, a second voltage conversion circuit, a second switch unit and a control circuit is provided. When the uninterruptible power supply performs a battery activation operation, the control circuit controls the first switch unit to provide the AC power received by the uninterruptible power supply to a terminal of a bypass path, controls the first switch unit to provide the output of a battery to the first voltage conversion circuit, controls the second switch unit to electrically couple the output terminal of the uninterruptible power supply to the other terminal of the bypass path, controls the charging circuit to stop charging the battery, and controls the first voltage conversion circuit to perform a DC-DC conversion operation. In addition, a corresponding battery activation operation method is also provided.

摘要: A power-switching device with interlock mechanism has a housing with a rotary knob, a slider slidably moved into a rotation range of the rotary knob, and an activation switch mounted on a sliding path of the slider. The activation switch has a control button located on an overlapped portion of the sliding path of the slider and the rotation range of the rotary knob. When the slider approaches the rotary knob, the activation switch is activated and the rotary knob is unable to rotate for being blocked. When the slider departs from the rotary knob, the activation switch is deactivated and the rotary switch is rotatable. Accordingly, when manually bypassing a UPS by turning the rotary knob, users will not forget to deactivate the activation switch, thereby avoiding damaging the UPS.

摘要: An on-line uninterruptible power system and an operation method thereof are provided. The on-line uninterruptible power system comprises a first switch unit, a second switch unit, a charging circuit, a DC-AC conversion circuit, a power factor correction circuit and a control circuit. When the on-line uninterruptible power system is in a line mode, the control circuit controls the operation of the power factor correction circuit to limit the magnitude of its input current to not exceed a first predetermined value.
