摘要： A power conversion apparatus capable of simultaneously discharging swap batteries even while reducing the number of power circuits includes a secondary converter configured to convert alternating current (AC) power into direct current (DC) power, a main battery connected to the secondary converter to receive the DC power, a replaceable swap battery block connected to the secondary converter configured for simultaneous discharge with the main battery, a switching circuit configured to turn on or off electrical connection between the replaceable swap battery block and the secondary converter, and a bypass circuit configured to turn on or off electrical connection between the swap battery block and the main battery.
