This paper proposes a novel topology of multilevel current source inverter which is suitable to apply in low/medium voltage. The proposed topology is capable of producing desirable bidirectional output current levels. Furthermore, it can employ symmetrical DC current sources as well as asymmetrical ones which is a significant advantage. Asymmetrical mode makes it possible to generate a great nu...

A multilevel inverter is capable of generating high-quality stepwise pseudo-sinusoidalvoltage with low THD , applicable to high-power and high-voltage systems. These types of topologiesmay require a large number of switches and power supplies. This leads to much cost, large size, andcomplicated control algorithms. Thus, newer topologies are being proposed to decrease the numberof power electron...

In this paper, a new configuration for symmetrical and asymmetrical multilevel inverters is proposed. In asymmetric mode, different algorithms are suggested in order to determine the magnitudes of DC voltage sources. The merit of this topology to the conventional symmetric and asymmetric inverters is verified by the provided comparisons. This topology uses a lower number of power electronic dev...

Asymmetrical structure is used to reduce the number of bridges and gate drive circuits and DC sources. This structure therefore provides the capability to produce higher voltages at higher speeds with low switching frequency which has inherent low switching losses and high converter efficiency. Newton Raphson (N-R) algorithm is investigated for the selective harmonic elimination (SHE) to calcul...
