H6 Inverter For Solar Power Generation With Automatic Tracking System

Abstract

Solar power is one of the most powerful renewable energy. Renewable energy is rapidly gaining importance an alternative energy resource since fossil fuel are depleting and their prices are fluctuating. The unique feature of the proposed method is the use of H6 type inverters instead of PWM inverters which eliminates the common mode voltage error thus reducing the transient oscillations, noise, etc. The microcontroller(PIC16F887A) is provided with tracking panel with automatic control, stepper motor and driver circuit. The microcontroller is used to control the solar panel. Opto isolation circuit is used to protect microcontroller and control circuit from power circuit. Isolated gate driver circuit and signal conditioning circuit are used for amplification and other purpose.
