**6. Experimental Results**

The proposed hybrid converter consists of a three-phase Vienna rectifier that was interleaved with 3L-NPC converter with total power of 2-KW was designed and implemented as per the specifications mentioned in Table 4. Figure 8 shows the requisite experimental results of the system, as depicted in Figure 5. As a Page: 9total grid supply voltage to the parallel connected converters will be same as showm in is Figure 8a–c. Figure 8a–d epitomize the results of total power that is supplied by the grid to both parallel-connected converters. 3.2% THD of total current also meet the IEEE standard. Figure 8b,f,j show the waveforms of total current, 3L-NPC and Vienna rectifier respectively. Half of the total current in 3L-NPC and Vienna rectifier show that the total system power divided among parallel-connected converters.

The detailed data in Figure 8c,g,k also verify that the total power has equally distributed in both parallel-connected converters, which verifies that the control algorithm works well in power-sharing. The currents drawn by NPC and Vienna rectifier, as shown in Figure 8h,l with THD 4.7% and 2.5%, respectively, also follow the IEEE standard.Moreover, the Vienna rectifier has less THD as compared to 3L-NPC, which also leads towards increased efficiency.

In Figure 9. the blue line shows the experimental results of the total dc-link voltage, while the yellow line represents a load current, as mentioned in table-IV. Finally, the whole setup of the implemented converter is shown in Figure 10 by labeling the main parts.
