| Summary: | Nowaday, electronic devices are very sensitive with harmonics. The needs for a free
harmonic and high rating power source is increased to meet the requirement from the
industries. This project is to eliminate THD using 9 level cascaded H-bridge of
multilevel DC–AC inverter. An Inverter can be broadly classified into single level
inverter and multilevel inverter. The result of 9 Cascaded H-Bridge Multilevel
Inverter level THD value are compared with 2 level inverter and 5 level Cascaded
H-Bridge Multilevel Inverter. The compared multilevel inverter to a single level
inverter has advantages like minimum harmonic distortion and higher power output.
An implementation of cascaded H-Bridge topology and a sinusoidal pulse with
modulation, synthesize a higher quality output power especially with multilevel
configuration. Experimental results are included to demonstrate effectiveness of the
proposed inverter. This project is to reduce THD contributed by the level of inverter. |
