    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.

    摘要: An inverting apparatus and a photovoltaic power system using the same are provided. The inverting apparatus includes an inverting circuit, a control circuit, and a voltage regulator-based ground detection circuit. The control circuit controls the power conversion of the inverting circuit. The voltage regulator-based ground detection circuit samples an input voltage of the DC input power, and performs voltage regulation and voltage division on the input voltage to generate a ground indication voltage. The electric potential of the output terminal of the voltage regulator is built based on a photovoltaic ground terminal of a photovoltaic module. The ground indication voltage is the voltage difference between an output terminal of the voltage regulator and a device ground terminal of the inverting apparatus. The control circuit determines whether a ground fault occurs to the photovoltaic module and enables a ground protection mechanism to control the inverting circuit when the ground fault occurs.
