The proposed multilevel inverter has been tested for both symmetrical as well as asymmetrical value of DC source. The proposed multilevel inverter are verified different algorithms for generating desired levels and for the same algorithm total standing voltage is also calculated.
The symmetric 11-level inverter based on the proposed topology requires 5 dc voltage sources. Each dc voltage source is 25 V so that the maximum output voltage is equal to 125 V. For this example of symmetric multilevel inverter, the proposed topology requires 12 IGBTs.
For the experimental studies, the 15-level inverter based on the proposed asymmetric multilevel inverter as shown in Fig. 14 is implemented. The proposed asymmetric 15-level inverter uses 3 dc voltage sources and 10 IGBTs. The dc voltage sources have values 25 V, 50 V and 100 V. So that, maximum 175 V output voltage is obtainable.
The proposed multilevel inverters use reduced number of switching devices for a specified number of output voltage levels in comparison with the conventional multilevel inverters and other non-conventional topologies. Hybrid topologies extracted from the proposed topologies are proposed for operating in higher voltage levels.
As the figure shows, the proposed symmetric multilevel inverter uses much lower number of IGBTs in comparison with the other topologies. For instance, for a 15-level inverter, the proposed topology uses 18 IGBTs whereas the presented topology in Ref. and the symmetric CHB multilevel inverter use 24 and 28 IGBTs, respectively.
Symmetry makes the Fourier coefficients of even order harmonics to zero. The generated harmonics in the inverter output mainly depends on the switching frequency of the PWM.
