Single phase sine wave inverter using Arduino: I hope all of you are fine and doing well. In today’s project , I am going to talk about our newly design project on arduino based pure sine wave inverter using sinusoidal pulse width modulation technique. I have already written a article on three phase sine wave inverter using arduino. So there are many people who are asking me to make a project on single phase sine wave inverter using Arduino also. I have made a proteus simulation and written a code in Arduino IDE. In this project, I have used Arduino Uno R3 for to generate PWM signals to drive MOSFET driver 1R2110. I will explain it in more detail in later part of this article. This inverter can convert 12 volt DC voltage to 220 volt AC volt with frequency of 50HZ and 60HzZ. User can select either 50Hz or 60 Hz according to their requirement. H bridge topology is used to convert dc voltage into ac voltage. Step up transformer is used to step up output of H bridge to 220V AC. After step up transformer, a LC filter is used to get pure sine wave from pulsating output wave.
Components used in single phase pure sine wave inverter using arduino
Followings are the main components used in single phase pure sine wave inverter using arduino. I provided a brief explanation of each component below:
- Arduino: Arduino Uno R3 is used to generate control signals for MOSFET driver using SPWM ( sinusoidal pulse width modulation technique). For more information on this technique, you can check my article on pure sine wave inverter using pic microcontroller. I have explained each and every thing in this article about SPWM, but that is all about pic microcontroller. Best concept is same so you can apply these concepts to Arduino while writing your code.
- MOSFT driver IR2112 : MOSFT driver IR2112 is used to driver four MOSFET connected in H bridge configuration. It can drive both high side and low side MOSET’s. In H bridge, two MOSFET’s are used in high side configuration and two mosfets are used in low side configuration.
- H bride using MOSFET’s : H bridge is used to convert dc voltage in ac . H bridge operates in two direction, positive direction and negative direction according to PWM gating singals to mosfet. It generate both positive and negative half cycle of AC voltage.
