Original Abstract Submitted
in a power conversion device, each of a plurality of converter cells includes a pair of input/output terminals, a plurality of switching elements, and a power storage element electrically connected to the input/output terminals through the switching elements. a current-limiting resistor is connected to a path of ac output current of the power converter. a bypass switch is connected in parallel with the current-limiting resistor. a short circuit switch short-circuits an ac line between an ac circuit breaker and the current-limiting resistor. in a discharge operation mode, a control device performs power conversion operation by allowing switching of each switching element of each of the converter cells in a state in which the ac circuit breaker and the bypass switch are opened and the short circuit switch is closed.
