Selective harmonic elimination pulse width modulation based hybrid multilevel inverter topology with reduced components

IET Power Electronics, EarlyView., 2022
Abstract In this paper, a reduced switch count single‐phase hybrid multilevel inverter (MLI) is presented. Level generation unit (LGU) and polarity changing unit (PCU) are the two parts of the presented topology which are connected in series. Other advantages of the proposed topology include the reduced switch count, higher level generation with ...

Power quality enhancement in asymmetrical cascaded multilevel inverter using modified carrier level shifted pulse width modulation approach

IET Power Electronics, EarlyView., 2022
New modified carrier‐based level shifted pulse width modulation approaches for single‐phase trinary dc source fed cascaded H‐bridge inverters are proposed in this article. In order to suppress the lower order harmonics, the carrier frequency is often tuned higher. However, switching and electromagnetic interference problems have a significant influence

A new symmetric modular eleven‐level inverter using single and double source unit for low voltage applications with reduced number of switches

IET Power Electronics, EarlyView., 2023
This study introduces a new modular multilevel inverter that can produce five levels of positive voltage using only six power switches and five DC voltage sources. The basic unit is composed of a single‐ and double‐source (SDS) unit. SDS reduces the number of power electronic components, such as the insulated gate bipolar transistors, freewheeling ...
