Power balancing in five level inverters

2013 12th International Conference on Environment and Electrical Engineering, 2013
This paper presents a unique control scheme for achieving power balancing in recently proposed multilevel inverter topologies. Moreover, this strategy can be extended to any type of topology and to any number of output levels of multilevel inverter (MLI).Comparisons have been made between the power delivered by sources in two different topologies with ...

Parallel-connected five-level PWM inverters

IEEE Transactions on Power Electronics, 2003
Multilevel PWM inverters have significant advantages over the conventional one because of the capability of operating the motor with nearly sinusoidal current waveforms and higher output voltages. In order to increase the power rating of the inverter, connection in parallel would be effective in the present case.

Three-phase, Five-level Multi-level Inverter Topology

Electric Power Components and Systems, 2012
Abstract This article reports a three-phase multilevel inverter topology. The multilevel inverter configuration generates voltage levels similar to the corresponding well-known conventional diode-clamped, flying capacitors and cascaded H-bridge inverters but with fewer power circuit components and simplicity.
