Abstract
An uninterruptible power apparatus with a function of forced disconnection path is coupled between a grid and a load, and the uninterruptible power apparatus includes a bypass path, a power conversion module, a current detection unit, and a control module. The bypass path includes a switch unit, and the power conversion module is connected in parallel to the bypass path. The current detection unit detects a current flowing through the bypass path and transmits a current signal to the control module. The control module provides a turned-off signal to the switch unit when a first voltage of the grid is abnormal, and transmits a polarity of the current signal. The power conversion module generates a compensation amount according to the polarity, and generates an output voltage command according to the compensation amount and a voltage at an input terminal or an output terminal of the power conversion module.
