Medium and high voltage grid-connected three-phase inverter

What is a three-phase grid-connected inverter system?

In this paper, a new three-phase grid-connected inverter system is proposed. The proposed system includes two inverters. The main inverter, which operates at a low switching frequency, transfers active power to the grid. The auxiliary inverter processes a very low power to compensate for the grid current ripple.

What is a three-phase inverter?

This project focuses on designing and simulating a three-phase inverter intended for grid-connected renewable energy systems such as solar PV or wind turbines. The inverter converts DC power from renewable sources into AC power synchronized with the grid, enabling efficient and stable integration of renewable energy into the electrical grid.

What is a grid-connected inverter?

Grid-connected inverters are expected to have high power quality, high efficiency, and high reliability in renewable energy applications. Therefore, inverter topology and control techniques play important roles in grid-connected systems. Voltage-source inverters are connected to the grid via filters.

Can a three-phase inverter be used in grid-tied renewable applications?

This project simulates a three-phase inverter topology widely used in grid-tied renewable applications, focusing on efficiency and power quality. Design a three-phase inverter that converts DC input to a balanced three-phase AC output. Implement sinusoidal Pulse Width Modulation (SPWM) to control output voltage and frequency.
