【 摘 要 】

It is proposed to analyze the performance of solar powered multilevel Neutral Point Clamped (NPC) inverter in low modulation index region using carrier based pulse width modulation (PWM). The solar panel act as variable DC voltage source input to the inverter. Using advanced carrier based dipolar PWM technique is used to have increased number of output voltage levels and reduced THD in low modulation index region.Simulation and measurement results using MATLAB/SIMULINK illustrate the advantage of the proposed PWM.
