Sinusoidal Pulse Width Modulation

A hybrid structured asymmetric switching capacitor multilevel inverter (ASC-MLI) is suggested in this work. The notion behind presenting this topology is to reduce the device count and DC sources as compared with conventional MLI. The step by step operating mode of single phase ASC-MLI is presented and by doing slight modifications the same configuration is used in three phase utility application and electric drive. The proposed configurations utilize major benefits of self-voltage balancing capability of capacitor voltage, which is independent from different load type and modulations index. To generate the switching pulse for corresponding switches the multi-carrier based sinusoidal pulse width modulation (MCS-PWM) technique is used; in addition to this simulation result are obtained using MATLAB/Simulink 2016b software version. Simulation results of an induction motor drive connected as three phase load highlights good performance of 17-level MLI.

The paper proposes an improved pulse width modulation algorithm to solve the voltage imbalance on DC capacitors for single-phase T-type inverter. By changing the modulation index, the residual states can be applied to the discharge/charge state on the DC capacitors to balance the voltage. The proposed algorithm is validated for application in single-phase T-type inverters in independent mode. The simulation and experimental results have confirmed the effectiveness of the improved pulse width modulation method for single-phase T-type inverter.
