Abstract: A power conversion control device controls a power converter. The power converter converts AC power into DC power. The power conversion control device includes a hardware processor coupled to a memory. The processor performs overcurrent protection by which operation of the power converter is suspended. The overcurrent protection is performed when an amount of output current of the power converter is equal to or greater than a threshold value. The processor permits restart of operation of the power converter having been suspended by the overcurrent protection. The restart is permitted only when the overcurrent protection is performed due to decrease in output voltage of the power converter. The processor restarts operation of the power converter after the restart of operation of the power converter is permitted.
