Implementation of Modified Five-Level Inverter Using a Reduced Number of Switches

In this manuscript, the design of a five-level inverter with a reduced number of switches suitable for industrial and commercial applications is developed. The multilevel inverter input can easily be integrated with a renewable energy source. Furthermore, the multilevel inverter provides full control for both output power factor reducing the filter weight, volume, and maximum power tracking. A modified version of cascaded H-bridge is used to reduce the switches up to six compared to the conventional model. The inverter switching angles are calculated using the SHE-PWM-GA technique to reduce lower order harmonics which suitable for medium-voltage high-power applications. This model is first tested using (MATLAB/Simulink)-simulation and then implemented on hardware to validate the results. The hardware setup consists of MOSFET switches and is driven by the Arduino controller for generating gate pulse.
