“…For the 17 levels of output voltage, 13 switches and 10 switches are used in [5]. The configured inverter produces a total harmonic distortion of 12.17% with seven levels of output voltage [7]. Only one DC voltage source is needed in order to operate at levels 3 and 5 in [7,11].…”

“…Lower-voltage DC sources are used to improve the voltage rating and solar photovoltaic system power quality. Switching Frequency Optimum (SFO) and Nearest Level Control (NLC) control approaches are used [7]. The control strategy of the neutral point clamped inverter is limited since only one basic vector may be selected as the optimal output during a control period.…”

This paper presents performance analysis of effects of modulation index on cascaded multilevel inverter fed single phase induction motor drive using closest level control technique. The modulation index is varied to analyze its performance. The effects on inverter output voltage, current, induction motor speed, electromagnetic torque and total harmonic distortion (THD) are considered. Both the load torque and modulation index are varied to determine the motor performance. The Closest (Nearest) control method is applied for generating firing pulses for the cascaded multilevel inverter power switches. By the application of this method, the switching losses are greatly mitigated when compared with high switching frequency of Pulse Width Modulation (PWM) schemes. MATLAB/SIMULINK software is used to obtain the system simulation results. The performance evaluation of this work was targeted on the modulation index range from 0.7 to 1.2 and for selected load torque values of 0 Nm, 2 Nm and 4 Nm. It is observed that modulation index affects the motor performance. When modulation index is 1.0 under different load torques, 6.2 % - 6.7 % range of voltage THD was obtained. When the modulation index becomes 1.2, motor speed and electromagnetic torque resulted to 1327 RPM and 20 Nm respectively with stability time of 0.7 sec under load torque of 4 Nm.
