چکیده
Multilevel inverters , covering a wide power range are currently considered as a better industrial solution for high dynamic performance and power-quality demanding applications. In this converter ,for specific time intervals fewer switches will be conducting so switching loss is also reduced . To generate gating signal Phase Disposition Pulse Width Modulation (PDPWM) technique is used here. This paper represents overall THD for different levels and different carrier frequencies. In this paper switching loss,conduction loss of inverter have been discussed and hence inverter efficiency can be calculated. Simulation studies are presented by using MATLAB/SIMULINK.
