The effectiveness of a permanent magnet synchronous motor (PMSM) drive managed by an automatic voltage regulator (AVR) microcontroller using field oriented control (FOC) with space vector modulation (SVM) and diode clamped multilevel inverter (DCMLI) is investigated. Due to its efficacy, FOC would be widely implemented for PMSM speed regulation. primary drawbacks 3-phase classic bridge appear r...

Abstract Four-level active neutral point clamped (ANPC) inverter becomes increasingly widely used in the renewable energy industry since it offers one more voltage level without increasing total number of switches compared to three-level ANPC inverter. The model predictive current control (MPCC) is a promising method for multi-level inverters. However, conventional MPCC suffers from high comput...

In this paper family of multilevel inverter topology with reduced number of power switches is presented. The proposed inverter can generate both even and odd level. The proposed topology is suitable for symmetric structure. The proposed symmetric inverter results in reduction of power switches, power diode and gate driver circuits and also it may further minimize the installation area and cost....

This article presents a modified sinusoidal pulse-width modulation (SPWM) scheme for five-phase, three-level neutral-point-clamped inverter. The deploys min–max function to inject the zero-sequence components into reference modulating signals; hence enabling effective utilization of DC-link voltage. Balanced split-input voltages were achieved through further incorporation adjustable voltage-dep...

This paper presents the development of a control scheme for a multilevel diode-clamped converter connected in a series–parallel fashion to the electrical system such that it can compensate for deviations in utility voltage (sag, surge, and unbalance) and act as a harmonic and/or reactive current source for a load. New carrier-based multilevel pulsewidth modulation techniques are identified to m...

In the previous literature, the introduction of the virtual-space-vector (VV) concept for the three-level, three-leg neutral-point-clamped converter has led to the definition of pulsewidth modulation (PWM) strategies, guaranteeing a dc-link capacitor voltage balance in every switching cycle under any type of load, with the only requirement being that the addition of the three phase currents equ...
