Design an Inverter for Hybrid System

In this paper, performance assesment was planned to be carried out by making inverter design which can be operated as grid – connected and stand – alone mode for hybrid energy systems. This paper describes the use of a general purpose microcontroller to generate the pulse width modulation (PWM) pulses for single phase inverter. A single phase inverter circuit is implemented with hardware setup and software program in C32 code. The main feature used in DSP and microcontroller is their peripherals to realize Pulse Width Modulation (PWM). This brings low cost, small size and flexibility to change the control algorithm without changes in hardware. Inverter output has been designed to be highly efficient. A laboratory inverter prototype using dsPIC32MX795F512L microcontroller is developed and results are presented. Simulations were carried out using Matlab Simulink software package
