Summary:Peak current control is a strategy widely used to control power electronic systems such as forward converters or two-level choppers. This strategy is characterized by constant switching frequency with good dynamic performance. This paper presents the application of this strategy to a multilevel voltage-source converter. The algorithm ensures that the converter output current follows the target reference, but it must be modified to include voltage-level selection within the multilevel converter. The principle of operation is introduced, and the implementation of the algorithm using a field-programmable gate array is demonstrated. Simulation and experimental results are presented to verify the control technique
