Synchronous Current Compensator for a Self-Balanced Three-Level Neutral Point Clamped Inverter
Figure 9
Experimental results. (a) PI controller response for the step input, (b) the line-line voltage (y-axis: 40 V/div and -axis: 30 ms/div), phase voltage (y-axis: 40 V/div and -axis: 30 ms/div), and phase current (y-axis: 5 A/div and -axis: 30 ms/div) of the inverter are shown for a step change in current demand.
