Three-level ASNPC converter implemented with an analogue command

The three-level Active Stacked Neutral Point Clamped converter is presented. The main advantage of this structure is the half reduction of the average switching frequency of all devices. This paper is focused on the analogue command of the 3L-ASNPC structure. The advantages of this modulation method are its simplicity and reduce cost. Experimental results are shown to validate the efficiency of this command method.
