An SVPWM-Based Multilevel Inverter for Photovoltaic Applications
The increased power quality demands along with rising power rating requirements become achievable with multilevel inverters which offer reduced electromagnetic interference (EMI) and harmonic distortion. The simultaneous processing capacity of added switches becomes crucial to manage as multilevel inverters increase their levels. The paper presents the implementation of space vector pulse width modulation (SVPWM) for neutral point clamped (NPC) inverters having two and three levels of configuration. The geometrical symmetry within the six sectors connects the procedure of switching on-time calculations to the strategy of on-time arrangement. The modeling of two and three level inverters through MATLAB/Simulink happens alongside experimental data verification of the system performance. The results indicate that photovoltaic cells can serve as an appropriate power source for the NPC inverter.
