Comprehensive Analysis of Integrated Renewable Energy Resources Based Multi Level Inverter Fed Various Motors Drives

Integrating renewable energy sources into the main grid enhances its resilience by diversifying power generation, reducing dependency on a single energy source, and reduces Total Harmonic Distortion and enhances power quality and improving grid stability. This approach also supports the development of smart grids, ensuring continuous, long-term energy supply from inexhaustible sources like wind and solar. Using inverters with motor drives fed by integrated renewable energy resources minimizes high-frequency switching harmonics, reducing electrical noise and mechanical vibrations, leading to quieter and more stable motor operation. Moreover, employing multi-level inverters (MLIs) increases efficiency by reducing switching and conduction losses, while offering superior torque and speed control. MLIs also enhance dynamic response and facilitate the implementation of advanced control algorithms, making them an ideal solution for motor control in renewable-powered systems. In this paper comprehensive analysis of Integrated Renewable Energy Resources (RERs) feeding Multi-Level Inverters (MLIs) like Neutral Point Clamped (Diode Clamped), Cascaded H-Bridge, and Flying Capacitor feeding various motor drives are tested in MATLAB Simulation environment. Simulation results show that the Cascaded H-Bridge fed BLDC motor gave optimum results in terms of torque, power factor and efficiency which leads to the sustainability for EVs and industrial drive applications.
