Abstract— This paper presents the simulation of three phase five-level modular multilevel cascade inverter based on double-star chopper-cell (DSCC). The multicarrier PWM techniques such as Phase disposition PWM (PDPWM), Phase opposition disposition PWM (PODPWM), Alternate phase opposition disposition PWM (APODPWM), and Phase shift PWM (PSPWM) is employed and a comparative study is done based on...

This paper presents the comparative study of three phase twenty five level diode clamped and cascaded H-bridge multilevel inverters. The comparison is made in respect of requirement of devices, quality of output voltage and reduction of total harmonic distortion at the multilevel inverter terminals. In this work multicarrier sinusoidal pulse modulation control methods of Phase disposition (PD-P...

In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...

In this paper a transformerless Static Synchronous Series Compensator (SSSC) to increase the power capacity of a 230 kV transmission line is proposed. In order to eliminate the transformer, a 15-level cascade H Bridge (CHB) inverter is employed within the proposed compensator structure to inject reactive power to the transmission line. The theory of instantaneous p-q power using in the compensa...

Open-end winding motors are used extensively in ship electric propulsion systems, which medium-voltage high-power inverters a critical component. To increase the system voltage and power density, dual five-level active neutral-point clamped (ANPC) inverter is proposed herein to drive open-end for propulsion. Each phase of this comprises two ANPC bridges all phases powered by common direct-curre...

This paper proposes a novel control design for Current-Fed Dual Active Bridge (CFDAB) converter in boost mode. The Double PWM plus Phase Shifted (DPDPS) modulation is applied to the due its considerable merits. A small-signal model developed output voltage stably Simulations of CFDAB were conducted verify proposed model. results show that system can achieve high performance, not only dynamic re...

Multilevel converter technology has emerged as a very important alternative in the area of high-power medium voltage energy control. The voltage source inverters produce a voltage or a current with levels either 0 or ±V dc they are known as two level inverters. To obtain a quality output voltage or a current waveform with a minimum amount of ripple content, they require high switching frequency...
