A novel matrix converter has been developed for 3-phase to 5-phase conversion using a novel space vector pulse width modulation. The matrix converter organized to generate 5-phase AC output voltage from 3-phase input voltage with help of SVPWM method; bidirectional power switches placed in matrix converter controlled by appropriate switching pulse. Space vector pulse width modulation (SVPWM) provides better utilization of applied input voltage, improved output voltage, reduced total harmonic distortion. The bidirectional switch used by the matrix converter decreases stress on the power switch and the influence of harmonic fluctuation in AC output voltage. When compared to traditional approaches, the suggested system offers improved output voltage and current control. Using MATLAB/Simulink and FPGA-cyclone controller, respectively, modelling and experimental results have been given to validate the proposed methodology.

Summary: A new basic unit of 25‐level asymmetric multilevel inverter topology is proposed in this article. The extended and cascaded topologies are developed to increase the output voltage level. Furthermore, to determine the magnitude of DC source values in each unit, two algorithms are presented. The proposed extended and cascaded structures are compared with other recent and conventional multilevel inverter topologies in terms of a number of DC sources, blocking voltage on the switches and cost of the inverter. The performance of the proposed topology is validated through the MATLAB/Simulink tool and laboratory setup for 25‐level output. The dynamic performances of proposed topology is confirmed with different loading conditions and their results are presented.

This paper elucidates the realization of multicarrier pulse width modulation(MC-PWM) based 7-level Z-source cascaded H-bridge inverter. MC-PWMtechnique is developed to generate switching pulses for Z-source inverter; itleads to boost the inverter output voltage with help of shoot through mode ofoperation. The output of Z-source inverter is connected to 7-level cascadedH-bridge inverter. Cascaded H-bridge inverter system much suitable for ACload drive, high voltage and high power and industrial applications. Thisproposed system provides reduced total harmonic distortion, improvedstepped output voltage and current, nearly sinusoidal output voltage and reduced voltage stress across the switching devices. The inductors andcapacitors values are selected based on the boosting level of Z-sourceinverter. The simulation results of proposed 7-level Z-source cascaded Hbridgeinverter with MC-PWM technique is verified usingMATLAB/Simulink.
