“…The adopted system parameters for all the MPDCC approaches are summarized in Table 1. The reason for using DABMI compared to single sided inverter is redundancy and to modulate high frequency fundamental [11]. The main inverter was supplied by 300V and the second inverter is being supplied with 150V to achieve multilevel voltage output waveform as shown in Fig.…”

“…The DC-link voltage proportional to the rms magnitude of the output voltage (or frequency to keep flux constant) can be controlled using a close-loop voltage controller. For a variable speed IM drives like traction drives, the fundamental stator voltage can be controlled indirectly by controlling the magnitude of DC-link voltages at the converter stage (output of the DC-DC converter) rather than the inverter stage in a conventional V/f control techniques However, the fundamental frequency of the inverter can be controlled by the suitable modulation at the inverter stage [35][36][37]. In [35], a multilevel converter using V/f operation of IM for open-end winding motor drive has been done.…”

A multilevel inverter (MLI) with staircase waveform having maximum number of voltage levels at any desired voltage (or frequency) of a variable voltage, variable frequency application can play an important role in the modern power conversion system. In most of the control and modulation techniques of MLI, the number of voltage level reduces with the reduction of modulation index that increases the harmonic and total harmonic distortions (THDs). The variable voltage application of MLI using a single DC source of variable magnitude is the elementary concept of the proposed control technique. A cascaded MLI having unequal voltage sources with controlled magnitude can be used to increase the number of voltage levels. The closed-loop voltage control technique and a multi-winding transformer-rectifier based AC-link system is used to obtain the multiple variable voltage DC sources for the cascaded MLI. A nearest level modulation based control technique has been implemented for the MLI to obtain the fixed level voltage waveforms with constant THD and reduced switching losses. The whole control algorithm for a nine-level inverter is simulated and results are experimentally verified on a laboratory prototype of the three-phase induction motor drives.

“…It is reliable because its outputs can be short-circuited when there is damage in either one of the cascaded inverters. In this regard, DABMI is functioning as a standard two level three-phase inverter [7]. The two isolated dc sources are used to cut the path of common-mode current flow and to achieve multilevel voltage waveforms [8].…”

This paper deals with controlling a grid-connected dual-active bridge multilevel inverter for renewable energy integration. The concept of direct power control is integrated with model predictive control algorithm, which is termed as predictive direct power control, to control the real and reactive power injected into the power grid. The proposed multilevel inverter allows more options of feasible voltage vectors for switching vector selections in order to generate multilevel outputs, and thereby obtaining high power quality in the power grid. By using the predictive direct power control, simulation results show that the proposed multilevel inverter produces lower power ripple and manage to achieve currents with low total harmonic distortion which are well within the IEEE standard. The modeling and simulation of the system are implemented and validated by MATLAB Simulink software.
