Reduced Switch 13 Level Inverter for Grid-Connected Applications

This work reports reduced switch cross-connected source (CCS) based thirteen level inverter for grid-connected applications. The proposed 13 level inverter is asymmetrically switched, and only eight switches are used to generate 13 level output. Multicarrier pulse width modulation technique (MCPWM) is proposed to control the output voltage and THD of the inverter. The inverter is simulated for resistive and inductive load with improved power quality, i.e., low THD output. The proposed inverter is further investigated for grid-connected applications through a proper grid control strategy. All the simulated results are further verified using a hardware-in-the-loop (HIL) simulation platform to confirm the feasibility of the proposed methods.
