The present invention provides a two-way AC power conversion device configured to input or output a first AC power. The two-way AC power conversion device comprises a digital control module and a power conversion module. The digital control module generates a control signal. The power conversion module sets the first AC power to be input or output according to the control signal. Wherein when the digital control module determines a real-time voltage signal of the first AC power is abnormal, the power conversion module switches to provide a ground voltage according to the control signal.
