Design and Implementation of the Firing Circuit of A SPWM Inverter Using Microcontroller

Behera, Sandeep (2015) Design and Implementation of the Firing Circuit of A SPWM Inverter Using Microcontroller. MTech thesis.



An inverter is the most important and basic device that converts DC electrical energy into AC. These inverters have variety of application in the field of power such as continuous power supply, motor drives (especially AC), etc. The inverters have a principal role in the field of conventional energy like since these play role in grid connected wind energy systems and Photovoltaic systems. The control strategies which are used in the inverters are similar to that used in DC-DC rectifiers. The inverters generally operate on the PWM techniques. The sinusoidal pule width modulation (SPWM) is the most popular technique used as gate pulse to the inverters now a days. There is various kinds of techniques to generate the SPWM. The SPWM switching signal is generated by different type of electronic boards such as FPGA’s and Audrino employing VHDL and coding languages such as C, C++, Python etc. This project is started by understanding the basic circuit of the inverter circuit employing SPWM switching signal. Here we will discuss the different SPWM generation techniques with the help of simple MATLAB SIMULATIONS, using on board microcontroller, ARDUINO UNO and LAB VIEW. And discuss the merit and demerits of various techniques. Furthermore we will also discuss the effect of the harmonics on the output voltage of the inverter
