摘要： A power conversion apparatus and a control method for a power conversion apparatus to reduce an amplitude of an output voltage of a converter when a grid is recovered from a fault, to ensure device safety. The power conversion apparatus includes a controller and a converter, and the controller is connected to the converter. The controller is configured to: after the output voltage of the converter is less than a first threshold, when the output voltage of the converter rises to be greater than a second threshold, reduce an active current output by the converter to a first current value, and reduce a reactive current output by the converter to a second current value, where the second threshold is greater than the first threshold.

摘要： In a first period having a first period length, first data and second data are alternately given to an inverter control unit. The first data has a first value indicating a length of time from the start point of time of the first period to a matching point of time as a point of time when a converter carrier takes a converter threshold value and an inverter threshold value corresponding to a second period having the first value as its length. The second data has a second value indicating a length of time from the matching point of time to the end point of time of the first period and an inverter threshold value corresponding to a second period having the second value as its length.
