Asymmetric multilevel inverters (MLIs) with unequal voltage steps (UVSs) are often
combined with the staircase modulation (SCM) technique to improve both voltage and …

The traditional inverters have the drawbacks of Harmonics as well as Total Harmonic
Distortion (THD). The analysis of THD and harmonics are studied in this paper by using …

In recent years, part of the efforts of the electric drive researcher has been focused on the
study of sensorless control algorithms that allow controlling the machine without a speed …

This paper presents novel analytical formulations for Line-voltage Total Harmonic Distortion
(LTHD) in three-phase Cascaded H-bridge (CHB) Multilevel Inverters with variable DC …

An efficient multicarrier SPWM for cascaded H-Bridge symmetrical multilevel inverter is
discussed here. The performance output levels of the CHB MLI is depends on number of DC …

The three-phase multilevel inverter output voltage waveforms are compared for the recently
proposed simple voltage source multilevel inverter space vector PWM technique, which …

The paper considers a PSIM model of the seven-level cascaded H-bridge voltage source
inverter, including a control circuits of its power switches (on the base signals' level). This …

This paper investigates multi-carrier PWM methods in multi-level inverters. Two new
MCPWM methods are introduced. This study proposes a new optimized MCPWM method to …

The ventilation system plays a vital role in ensuring the safety of people and means of
transportation. Fresh air is created in the tunnel mainly thanks to the exhaust fans arranged …

As the utilisation of renewable energy sources increased, the requirement of inverters
increased, In basic two-level inverter, the output waveform is produced by switching the DC …
