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...

This paper presents the performance analysis of asymmetrical cascaded H-bridge multilevel inverter based DSTATCOM in the distribution network. For this, seven level asymmetrical cascaded inverter based DSTATCOM is proposed for the compensation of 11 kV distribution network. The paper also presents the comparative analysis for different asymmetric inverters. For this, 7,9,11 and 13 levels with u...

Multiplicity of the triangular carrier signals is a criterion for extension sinusoidal pulse-width modulation, SPWM, to number output voltage levels per phase-leg in cascaded H-bridge (CHB) multilevel inverter (MLI). Considering medium and high applications where appreciable from CHB MLI needed, commensurate either classical level- or phase-shifted SPWM scheme this inevitable. High-quality wave...

This letter proposes a multilevel inverter (MLI), which can be considered to belonging the cascaded H-bridge (CHB) family. In proposed MLI, some of H-bridges are connected dc-sources, whereas most only floating capacitors. A boosting circuit is integrated in CHB, permits charging capacitors, enabling higher voltage at inverter's output with respect dc-sources total one. feature essential applic...

Pulse width modulation (PWM) is a powerful technique employed in analog circuit convert with microprocessor based digital output. Besides, Pseudo Random Multi Carrier (PRMC) involves two random PWM strategies to minimize the harmonic order for 9- level cascaded multilevel H-bridge (CHB) inverter and 9-level Modular Multilevel are introduced. The design mainly focuses on (Pulse Width Modulation)...

Aimed at the pulse width modulation (PWM) voltage noise and power imbalance in three-phase cascaded H-Bridge (CHB) inverters, a modified random PWM (RPWM) strategy, named power-balanced RPWM (PB-RPWM) is proposed this paper. The PB-RPWM strategy mainly includes three steps: (1) signals are generated by compared wave with level-shifted carriers; (2) circularly distributed between CHB units logic...
