“…A number of PWM techniques such as modulation frequency, harmonics mitigation, space vector, and carrier technique are used in multilevel power converter applications. In this study, a new control technique suggested by [16], MASPWM technique, is designed and used to build a novel control circuit to produce PWM pulses of a 15-level inverter with NZL and with ZL MI as explained in Figure 3. At the start of the MASPWM controller, reference signaling with range present the requested output level of the MI is made.…”

“…The THD obtained for the output voltage is 6.86%. Also, in 2018 [16], three cells inverter with 12-swithes and three input DC sources of (1, 3, 9) Vdc was simulated by MATLAB to get 27-level output voltage made on a modified absolute sinusoidal PWM (MASPWM) strategy. The AC voltage and current distortion values of a three-phase circuit and resistor-inductor (RL) load were 0.67% and 0.0857%, while with single-phase the THD values were 1.165% and 0.238%, respectively.…”

“…The lowest distortion value of the output waveform at 1kHz is 6.71%, while with 2kHz is 6.59%. In 2020 ANTAR et al [22], the same power and control circuits suggested by [16] used for sensorless speed and torque control of an induction motor at different operating conditions. The system gave good response and quality.…”

The advantage of multilevel inverters is to produce high output voltage values with distortion as minimum as possible. To reduce total harmonic distortion (THD) and get an output voltage with different step levels using less power electronics switching devices, 15-level inverter is designed in this paper. Single-phase 11-switches with zero-level (ZL) and none-zero-level (NZL) inverter based on modified absolute sinusoidal pulse width modulation (MASPWM) technique is designed, modelled and built by MATLAB/Simulink. Simulation results explained that, multilevel inverter with NZL gives distortion percent less than that with ZL voltage. The THD of the inverter output voltage and current of ZL are 4% and 1%, while with NZL is 3.6% and 0.84%, respectively. These results explain the effectiveness of the suggested power circuit and MASPWM controller to get the required voltage with low THD.

“…Various pulse-width modulation (PWM) techniques have been developed for industrial applications. The most widely used PWM schemes for three-phase voltage source inverters are carrier based sinusoidal PWM [6][7][8][9][10][11][12][13][14] and space vector PWM (SVPWM) [15][16][17][18][19][20][21][22][23]. The output voltage per phase for a sinusoidal PWM based three phase converter is limited to 0.5Vdc (peak value) and the line-to-line RMS voltage is 0.612Vdc.…”

With increasing research and advancement in solid-state power electronic devices and microprocessors, various inverter control techniques employing Pulse Width Modulation (PWM) are becoming popular especially in AC motor drive applications. The most commonly used techniques are Sinusoidal PWM (SPWM) and Space Vector modulation PWM (SVPWM). SVPWM is considered to be superior to the SPWM because of better DC bus utilization. In this paper, a real-time digital implementation of SVPWM algorithm for three-phase two level inverter using dSPACE DS1104. The results obtained from the experimentation are closer to that of simulation, which confirms the validity of the implemented algorithm.

“…In the same year [9], four voltage sources, seven power switches, three additional diodes and seven driver circuit were used in order to implement nine-level switches including the zero-level with output voltage and current THD of 5% and 1.03%, respectively. In 2018 [10], a multilevel three-H-bridge inverter with DC inputs of (Vdc, 3Vdc, 9Vdc) was built to get 27-level voltage output depending on a modified absolute sinusoidal pulse width modulation (MASPWM) strategy. The output current and voltage distortion values for three-phase circuit were 0.0857% and 0.67%, while the THD values of the single-phase were 0.238% and 1.165%, respectively.…”

<p>Currently, multilevel inverter (MLI) has been chosen over conventional inverter because of less harmonic distortions and higher output voltage levels. In this paper, 15 level inverter with reduced number of power switching devices is designed. Different output voltage levels can be obtained including zero level or with none zero level (NoneZero level). Single phase MLI inverter with 7 switches is built, simulated, and implemented practically. The system depending on modified absolute sinusoidal pulse width modulation (MASPWM) controller strategy is adopted. Simulation results clarified that MLI with NoneZero level provides output voltage with total harmonic distortion (THD) percent less than with zero level. The THD of the 15 level output voltage with zero level is 3.39%, while with NoneZero level is 3%, respectively. The system is tested at different output levels. The THD values at different output voltage levels is reduced by 12% depending on NoneZero level state. Depending on what has been achieved, the system has been implemented practically with NoneZero<br />level and the THD value was 3.1%. These results prove the success of the suggested MLI circuit and MASPWM controller to obtain the required voltage level and THD.</p>
