Abstract:
This paper proposes a new asymmetrical type
fifteen level inverter with minimum number of power
electronic switches to reduce THD. The proposed inverter
consist of three DC voltage sources, seven main switches
and four switches of H-bridge inverter to generate fifteen
level output. The proposed multilevel inverter is very
simple to construct and is suitable for medium voltage and
high power applications. Different methods of calculating
the switching angles are presented and the results are
compared. The performance of the proposed fifteen level
inverter is compared with other topologies. The simulation
is performed using MATLAB/SIMULINK software to
verify the function of the proposed inverter.
