This paper highlights the decrease of system complexity by comparing different multilevel inverter architectures with the nearest level control method. Performance measures like component count, voltage stress across switches, total standing voltage, and total harmonic distortion are analyzed. 12 switches are used in Topology-I while only 10 are needed in Topology-II. Further, Topology-I employs 4–6 switches at any given time whereas the number of switches triggered to produce 25 levels in Topology-II is only 4. Topology-II is more efficient than Topology-I in terms of fewer components and less voltage stress. THD performance is evaluated for both the topologies. The findings of Topology-II strengthen the optimization of switch count and better performance that makes the multilevel inverter technology more favorable for a wide variety of power conversion applications.

摘要

This paper highlights the decrease of system complexity by comparing different multilevel inverter architectures with the nearest level control method. Performance measures like component count, voltage stress across switches, total standing voltage, and total harmonic distortion are analyzed. 12 switches are used in Topology-I while only 10 are needed in Topology-II. Further, Topology-I employs 4–6 switches at any given time whereas the number of switches triggered to produce 25 levels in Topology-II is only 4. Topology-II is more efficient than Topology-I in terms of fewer components and less voltage stress. THD performance is evaluated for both the topologies. The findings of Topology-II strengthen the optimization of switch count and better performance that makes the multilevel inverter technology more favorable for a wide variety of power conversion applications.
