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.

Two-way AC power conversion device

The present invention provides a voltage control method for controlling a power supply. The voltage control method comprises the following steps: obtaining a present output voltage value associated with a present gain value; obtaining a predetermined output voltage value associated with a predetermined duty ratio; calculating a target gain value, corresponding to the predetermined duty ratio, according to a gain value formula; performing a weight calculation on the present gain value and the target gain value for generating a buffer gain value; and setting an output voltage command according to the buffer gain value. Wherein the buffer gain value is between the present gain value and the target gain value.
