“…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.

“…The 9-level inverter proposed in [15] uses a cascade structure of 3-level T-type and HB that can extend the LMR till peak phase fundamental 0.607V dc while supplying an u.p.f load. There are many polygonal voltage space vector structures used to eliminate the lower order harmonics from the motor phase -such as 12 sided polygon eliminates only 5 th and 7 th [16], 18 sided polygon eliminates 5 th , 7 th , 11 th and 13 th [17]. Higher the sides of the polygon, higher harmonics range are eliminated from the phase voltage [18].…”

“…The harmonic suppression was extended to 12 GHz, and the suppression level was higher than À20 dB. Pramanick et al (2015) designed a method to suppress the low-order harmonics. Through the combined pulse width modulation (PWM) control of two inverters, the 5th and 7th harmonics were suppressed, and the effectiveness of the method was verified by experiments.…”

Purpose This study aims to focus on the grid connected inverter. Design/methodology/approach The grid connected inverter for harmonic suppression was designed, the topological structure of the inverter and the design of LCL filter were analyzed, then a PIR controller was proposed and finally simulation and experiment were carried out. Findings The simulation results showed that the distortion rates of the 5th, 7th and 11th harmonics under PIR control were 0.14%, 0.13% and 0.06%, respectively, which were significantly lower than that under PI control. The system test results also showed that the current waveform under PI control was rough and total harmonic distortion (THD) content was 3.8%; under PIR control, the grid connected current waveform was relatively smooth, with fewer spikes and burrs, and the THD content was 1.9%, indicating that the harmonics were effectively suppressed. Originality/value The experimental results verify that the inverter and PIR controller designed in this study are effective for harmonic suppression. This work makes some contributions to the improvement of the effect of harmonic suppression and promotion of the better application of grid connected inverter.
