21-level CSD Based Solar Multilevel Inverter Fed Induction Motor Drive

As the demand for electricity increases, renewable energy is considered to be the most promising distribution today. Comprehending an advanced solar multilevel inverter with soaring feat, by denominating a customization system configuration. The modular configuration consists of a DC-DC converter module and a DC- AC inverter module. The DC bus acts as a modern shared record provider between them. Realize parallel and redundant operation of inverter modules, unless there is no verbal communication link between them. Here, the new inverter topology is utilized to the system. The cascaded switching diode multilevel inverter was selected as a safe and suitable topology. Because of its flexibility of control and a small range of switches are regarded its foremost advantages. The duty cycle exchange control provided to the multilevel inverter helps stabilize the DC energy supply. This control aids in the power distribution around the switches. This monitoring helps to cut down on heat and conduction losses. THD is likewise quite low in this case. The use of photovoltaic multilevel inverter-fed induction motor power is as well described. The motive of this article is to attain the secure output of the photovoltaic multi- level inverter and its single-phase 21-level CSD-MLI (Cascaded Switched-Diode) inverter topology application. The motor drive operation will use a designed solar multi-level inverter to display speed-torque characteristics of SPIM. It is acquired with the aid of modelling the system using MATLAB software.

I. Introduction

Nowadays, the sun is a sustainable energy source in the world, and it powers the world with its energy. The rapid growth of solar energy projects has met the global demand for electricity. It plays an important role in renewable energy because it is a clean and affordable energy source. It also helps people discover their talents in society and provides a platform for researchers. Among renewable energy sources, solar energy is always the first choice [1]. It has no moving parts, so there is less maintenance and low risk. It also provides the most predictable output, and the installation is faster and with fewer conductor quantities. Nowadays, the integration of solar energy systems and public grids has received widespread attention. The system does not require a battery system, is effectively used, and has no storage loss [2]. It is most widely experimented on rooftops to decrease the consumer's electricity bills. In a distributed network, it has proven to be the best power- sharing renewable resource [3]. Cascaded H-bridge multilevel inverters are a suitable choice for distributed photovoltaic power generation systems [4]-[5].
