Repetitive schemes, aimed for harmonic compensation, are formed by the interconnection of delay lines. They are usually implemented in a digital way, where delay lines are replaced by discrete delays. Each discrete delay is obtained as the ratio between the required delay time in continuous time and the sampling period. A problem arises whenever the delay(More)
This paper presents the modelling and control of the three-phase grid-connected modular multilevel converter. Based on the obtained model, a combined controller is proposed with the aim to regulate and balance the total energy on each converter phase, minimize circulating currents, and inject a current in phase with the grid voltage. For this, the proposed(More)
