Abstract: A flying capacitor multilevel converter having active neutral-point-clamped topology with an output LCL-filter, wherein the converter comprises an overcurrent mode controller. The overcurrent mode controller is adapted to receive a converter current reference and measured converter current, to form an overcurrent band having an upper and a lower value, the upper value being higher than the converter current reference and the lower value being lower than the converter current reference, and to block gate control signals when the measured converter current is positive and higher than the upper value or when the measured converter current is negative and lower than the lower value.
