Description

This paper describes the design of a 5-level multilevel inverter for grid connected renewable energy systems simulated using MATLAB. The inverter developed works with an input voltage of 164 V and a well-regulated output voltage of 325.4 V, with the switching frequency fixed at 20 kHz for efficiency, while controlling the modulation index (M) for proper voltage regulation. The performance review of the inverter such as THD and power factor were simulated with MATLAB. It is found that the voltage quality has been greatly improved and harmonic vicious generation has been diminished when compared with traditional inverter. The high-quality of output voltage provided by the inverter also makes it ideal for use with renewable energy systems. The simulations also demonstrate the efficiency of the inverter when controlling power for grid connection, revealing its capability to offer secure and low-cost renewable energy solutions. Performance evaluations indicate improved voltage waveform quality and higher efficiency of the system, which makes it promising for future renewable energy connected applications. The fact of using MATLAB simulations to verify our designs further proves its feasibility and efficacy in handling the challenges of power conversion in sustainable energy systems. 2026 IEEE.
