  "textContent": "In a power conversion apparatus, a connection switch electrically connects between a neutral point of star-connected plural-phase windings and each of a negative terminal of a first battery and a positive terminal of a second battery while turned on, and cuts off an electrical connection between the neutral point and each of the negative terminal of the first battery and the positive terminal of the second battery while turned off. A control unit performs a switching control task of upper- and lower-arm switches while the connection switch is in an on state. A determining unit determines whether to execute a short-circuit control task that turns on one of the upper- and lower-arm switches of each switch unit and turns off the other thereof. A cutoff unit turns off the connection switch when the determining unit determines to execute the short-circuit control task.",
