Abstract
Nowadays, inverter which is also known as a DC-AC converter is one of the most popular parts in electrical devices that converts direct (DC) current to alternating current (AC) at the desired output voltage and frequency. This project presents development of a Unipolar Sinusoidal Pulse Width Modulation (SPWM) for single phase full bridge inverter using Field Programmable Logic Array (FPGA). The Unipolar SPWM is employed to control the output voltage magnitude of the inverter. Altera DE2-70 board with 16 bit serial configuration devices is used as a controller for the implementation of the SPWM inverter. Computation of the turn-on and turn-off times of the SPWM is developed using Matlab. To verify the proposed FPGA-SPWM, voltage amplitude regulations are carried.
