“…Implementation of the carrier-based PWM technique exists in two methods. The direct digital technique has a pre-calculated inverter state, time length of each carrier, and modulation cycle employing space vector theory (Hava et al, 1999;Gopalakrishnan and Narayanan, 2014). The indirect technique works with carrier triangle intersection technique.…”

Pulse width modulation (PWM) methods are used to control the switching sequence operations of conventional multilevel inverters (MLIs) and reduced switch multilevel inverters (RSMLIs). Many researchers proposed various RSMLIs with their switching sequence operation and PWM control techniques. However, the switching operations of RSMLIs are not similar to conventional MLIs, which are a major problem of switch control. Logical equations are proposed for the operation of RSMLIs with the multi-carrier PWM methods like alternative phase opposition disposition (APOD), phase opposition disposition (POD), and phase disposition (PD). To operate the individual switch in symmetrical and asymmetrical RSMLI, logical operators are used to produce required pulse sequence from the sequence of PWM method and their analysis is not present in previous works. The proposed methodology can be applied to PV systems for efficient operation. The proposed methodology and binary representation of PWM method are analyzed on various RSMLIs for seven-level output voltage to operate each individual switch. Control of individual switching sequence and the operation of RSMLIs are simulated using MATLAB/Simulink. THD comparison is presented for RSMLI, DCL MLI, and SCSD MLI with various PWM methods.

“…The widely used technique for MLIs is SVM method due to the ease of implementation in digital environment, higher DC‐voltage utilization and lower THD. Moreover, SVM is the most comfortable and suitable modulation for implementation of the DC‐link voltage balance methods for DCMIs 1,23‐26 . Therefore this method receives much attention in the recent literature.…”

Summary This paper presents cascaded topology of three‐phase neutral‐point‐clamped converters (NPCC)s. Two or more NPCCs are cascaded in their AC sides through transformers. This multilevel inverter (MLI) is a transformer‐based single‐source inverter with trinary asymmetry. Compared with conventional and advanced diode‐clamped multilevel inverters, the proposed MLI achieves more levels on output voltage. From cost, number of components, volume, complexity and efficiency aspects, the proposed inverter is an optimized and advanced inverter. An individual space vector modulation (SVM) method has been developed for voltage control of the inverter. The neutral‐point voltage of the inverter is balanced conveniently by the SVM method. The proposed inverter is suitable for constant‐frequency applications. Simulation and experimental results of a 17‐kVA prototype verify the efficiency of the proposed arrangement.

“…In order to increase the voltage from the solar panel boost converter is used. The modulation index used in three phase inverter is based on space vector modulation (SVM) technique discussed in literature [7][8][9], depicts minimization of switching frequency. In the event of reducing harmonics and high dc-link voltage, three level inverter plays a prominent role [10].…”
