A scheme for a three-level voltage space phasor generation with common-mode voltage elimination is proposed. An open-end-winding induction motor, fed from both ends by two threelevel inverters, which are realised by a cascading two two-level inverter, is used in this configuration. The voltage space vectors of individual three-level inverters, which generate the same commonmode voltage in the i...

 The advent of the transformerless multilevel inverter topology has brought forth various pulse width modulation (PWM) schemes as a means to control the switching of the active devices in each of the multiple voltage levels in the inverter. An analysis of how existing multilevel carrier-based PWM affects switch utilization for the different levels of a diode-clamped inverter is conducted. Two ...

This paper presents the implementation of Single Phase 7 level Multilevel DC link (MLDCL) Inverter with Half Bridge Cell topology. For N level inverter, (N-1)/2 half bridge cells are required with the same number of voltage sources. In this inverter topology, 3 Half Bridge Cells are used along with 3 voltage sources, each have 100V DC. These half bridges are connected in series to form a Multil...

A multilevel inverter is mainly used to synthesize a near sinusoidal voltage from several levels of dc voltages. As number of levels increases, the synthesized output waveform has more steps, which provides a staircase wave that approaches a desired waveform. The harmonic distortion of the output wave decreases, approaching zero as the number of voltage levels increases. This paper spotlights t...

Recently, the evolution of single phase multilevel inverters has been escalation due to its preference over traditional one. In this paper proposed a new topology of single phase Nine level inverter with less number of power elements for grid connection. In this proposed inverter have ten switches and their switches operate with fundamental frequency. The proposed inverter produced nine level o...

The standard solution for the traction system in battery powered electric vehicles (EVs) is a two-level (2L) inverter feeding a three-phase motor. A simple and effective way to achieve a three-level (3L) inverter in battery-supplied electric vehicles consists of using two standard three-phase 2L inverters with the open-end winding connection of standard three-phase ac motors. The 3L inverter so...

This paper presents the comparison of various multicarrier Pulse Width Modulation (PWM) techniques for the Cascaded Hybrid Multi Level Inverter (CHBMLI). Due to switch combination redundancies, there are certain degrees of freedom to generate the five level AC output voltage. This paper presents the use of Control Freedom Degree (CFD) combination. The effectiveness of the PWM strategies develop...
