Design of Single-Phase Grid-Tied Inverter with Maximum Power Point Tracking

Abstract Renewable energy has been used in many electrical appliances to make our world pollution-free, environmentally friendly, and reliable. In this paper, solar power as renewable energy is used indifferent types of inverters to convert all DC power to AC power which will fed into the electric utility in case any power outages happen. The grid-tied inverter (GTI) uses a local oscillator to synchronize the frequency (range: 50 or 60 Hz) with the grid. In GTI operation there are two different types of charge controllers used such as Pulse Width Modulation (PWM) and MPPT. MPPT is an electronic converter that converts a solar panel’s high-voltage DC output to lower DC voltage to charge the battery bank or the utility grid. In this paper main objective is to review the GT inverters with MPPT techniques with different scenarios. The aim of this paper is to discuss and research different types of GT inverters with different charge controllers.
