Abstract |
|
This paper present a asymmetrical cascaded 7 level multiinverter using fixed frequency carrier based pulse width modulation technique.The multilevel inverter is used to reduce harmonics. Here we are comparing single phase 7 levels and 3 phase seven level topology and thus reducing THD less than 5%. In asymmetical cascaded single phase MLI by using only 2-H bridges with 8 switches we can get 7 level output voltage where as cascaded three phase MLI 7 level output voltage is obtained by using 6-H bridges with 24 switches. |
