In this paper, a hysteresis current control technique for a single-phase five-level inverter with cascaded H-bridge topology is proposed. The basic study to implement the logic for correct voltage-level selection, various schemes available in the literature have been described and will provide a useful framework and point of reference for the future development of hysteresis modulation for mult...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...

The multilevel inverter power structure plays a vital role in the power industry. It is easier to produce a high-power, high-voltage inverter with the multilevel structure. The topologies of multilevel inverter have several advantages such as lower total harmonic distortion (THD), lower electromagnetic interference (EMI) generation, reduction of voltage ratings of the power semiconductor switch...

Multilevel converters offer advantages in terms of the output waveform quality due to the increased number of levels used in the output voltage modulation. This advantage is particularly true for cascade H-bridge (CHB) converters that can be built to produce a large number of levels owing to their modular structure. When increase the number of levels it requires more number of switches, it impl...

The concept of multilevel inverters introduced about 20 years ago entails performing power conversion in multiple voltage steps to obtain improved power quality, lower switching losses, better electromagnetic compatibility, and higher voltage capability. The benefits are especially clear for medium-voltage drives in industrial applications and are being considered for future naval ship propulsi...

Minimum Total Harmonic Distortion (THD) is one of the most important requirements from multilevel inverter concerning good Power Quality. This paper presents the optimization of THD in 13 level Cascaded Multilevel Inverter with unequal dc source using Genetic Algorithm (GA). THD minimization is taken as an optimization problem derived from Selective Harmonic Elimination Pulse width Modulation (...

Multilevel inverters have several advantages over the conventional two level inverters due to their lower switching frequency, reduced switching stresses, low EMI and EMC issues, ability to achieve high voltage levels, low THD etc. Multilevel inverters can synthesize the desired voltage from several levels of DC voltages.

This paper analyses synchronization strategies for cascaded H-Bridge multi level inverter topologies with carrier based sinusoidal phase shifted pulse width modulation technique. In phase shifted pulse width modulation technique, a separate carrier is used for each H-Bridge. The carriers are generally phase shifted from each other by π/n Rad (n=No. of HBs). Hence, the positions of carriers w.r....
