SHEPWM Based New Hybrid Multilevel Inverter Topology with Reduced Switch Count [PDF]
2019 21st European Conference on Power Electronics and Applications (EPE '19 ECCE Europe), 2019 In this paper, a new single-phase hybrid multilevel inverter topology is proposed with reduced switch count. The basic unit of the proposed topology is capable of generating 13 levels at the output. A higher number of levels can be generated by extending the basic unit. Two different extensions of the basic unit have been proposed in the paper.

LCL Grid Filter Design of a Multimegawatt Medium-Voltage Converter for Offshore Wind Turbine Using SHEPWM Modulation [PDF]
The switching frequency of medium-voltage highpower converters is limited to about 1 kHz due to semiconductor junction temperature constraint. The frequency band between the fundamental and carrier frequency is limited to a little more than one decade ...

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.We propose a novel five‐level active‐neutral‐point‐clamped converter utilising reverse blocking IGBT (RB‐IGBT). The inverter configuration significantly reduces conduction losses, as only two switches are on the current paths in some switching states. We also propose an optimised state machine‐based modulation strategy.
