Abstract-Three-phase multilevel inverters are used in many medium-and high-power applications such as motor drives and grid-connected systems. Despite numerous PWM techniques for multilevel inverters have been developed, the impact of these modulation schemes on the peak-to-peak output current ripple amplitude has not been addressed yet. In this paper the analysis and the comparison of current ripple for two-and three-level voltage source inverters are given. Reference is made to optimal and popular modulation, so-called centered PWM, easily obtained by both carrier-based modulation (phase disposition, with proper common-mode voltage injection) and space vector modulation (nearest three vectors). It is shown that the peak-to-peak current ripple amplitude in three-level inverters can be determined on the basis of the ripple in two-level inverters, obtaining the same results as by directly analyzing the output voltage waveforms of the three-level inverters. This procedure can be readily extended to higher level numbers. The proposed analytical developments are verified by both numerical simulations and experimental tests.Index Terms-Multilevel inverters; three-level inverter; output current ripple; carrier-based PWM; space vector PWM.

“…Many methods have been developed to decrease the number of switches [8]. Modulation strategies applied to multilevel inverters are selective harmonics elimination [9] [10], carrier based pulse width modulation [11] [12], space vector modulation [13] [14] and fundamental frequency modulation [15] [16]. The pulse-width modulation (PWM) control [17] is the most efficient method of controlling output voltage within the inverters.…”

Multilevel inverters have become more popular in high power and high voltage application. They have a unique structure which makes it possible to reach high voltages with less harmonic content. Harmonic content of the output voltage waveform decreases as the number of output voltage level increases. The main advantages are lower Total Harmonic Distortion (THD), less stress on the power switches and higher efficiency. However, increase in the device count due to increased voltage levels makes the control method complex and hence expensive. This paper presents a nine level inverter with reduced DC sources which is capable of obtaining all additive and subtractive combinations of input DC levels. This topology requires less power switches compared to conventional multilevel inverter and less gate drives. The proposed topology is presented through a nine-level inverter with an appropriate modulation scheme and detailed simulation has been carried out in MATLAB/Simulink. A comparison is made between proposed topology and the conventional multilevel topology on the basis of device count, number of levels in the output voltage and THD.
