Abstract:
This seminar report proposes a single phase 9-level multilevel inverter topology
fed from a PV panel with a multicarrier phase disposition sinusoidal pulse width
modulation scheme (PWM) for the generation of gate signals for power switches.
Desired number of output levels: 3, 5, 7 and 9 is obtained by controlling modula
tion index. The proposed inverter configuration was subjected to an R-L load and
respective number of desired output voltage was synthesized for different modulation
index. An LC filter is modelled to obtain pure sine wave output and its given to
the load. THD value for output current and voltage of the proposed configuration is
determined. Simulation has been carried out to study the performance of the pro
posed topology in MATLAB/SIMULINK R2010a environment. Simulation results
analyzed and results presented for circuit.
