Abstract
|
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 devices such as switches, IGBTs, diodes, related gate driver circuits and DC voltage
sources. Owing the lower amount of requirements, it has lower total costs and needs less installation
area. Also the control strategy has less complexity. The proposed converter can generate all the desired
output voltage levels with positive and negative values. To confirm the practicability of the proposed
inverter, simulation and experimental results are provided which are in good agreements.
