Experimental analysis of sensor (solar PV) based variable frequency multicarrier PWM techniques for enhanced power quality in bioengineering systems

This study presents the design and analysis of a symmetrical 7-level modular multilevel inverter (MMI) integrating photovoltaic (PV) solar modules using multicarrier pulse width modulation (MCPWM). The proposed MMI reduces the number of switches, DC sources, and power diodes compared to conventional...

description This study presents the design and analysis of a symmetrical 7-level modular multilevel inverter (MMI) integrating photovoltaic (PV) solar modules using multicarrier pulse width modulation (MCPWM). The proposed MMI reduces the number of switches, DC sources, and power diodes compared to conventional topologies. To improve the fundamental voltage and total harmonic distortion (THD), the frequency and amplitude of the carriers were varied. The MMI configuration includes three solar PV panels, seven switches, and three diodes, implementing various PWM schemes such as Phase Disposition (PD), Alternative Phase Opposition Disposition (APOD), Phase Opposition Disposition (POD), Variable Amplitude (VA), and Variable Frequency (VF). MATLAB/Simulink simulations yielded 94.7 % efficiency, 17.28 % THD, 2.34 % capacitor voltage ripple, and 66.7 V voltage stress across switches. The proposed MCPWM methods were validated through hardware implementation using an FPGA XC3S500-320 F chip, confirming the simulation results.
