摘要： An inverting apparatus and a control method thereof are provided. The inverting apparatus includes an inverting circuit, a detection circuit, and a control circuit. The control circuit is coupled to the inverting circuit and the detection circuit and configured to provide a control signal to control the inverting circuit so as to adjust a voltage value of an input voltage into a command voltage represented by the control signal. The control circuit calculates a voltage difference between the detected input voltage and the command voltage so as to determine whether the voltage difference is greater than a preset value. When determining that the voltage difference is greater than the preset value, the control circuit sets the voltage value of the command voltage as the voltage value of the current input voltage.
