Pure Sine Wave Inverter Circuit Using Microcontroller Ic. Pure sine wave inverter using pic microcontroller is designed in this project. Pwm controllers ic sg3525 use and application.
How to make h bridge and diagnose problems. In a previous article i have shown you how not to make a modified square wave inverter by addressing the problems associated with it. These pure sine wave inverters are very expensive where the modified square wave inverters are inexpensive.

H bridge mosfets are operated in such a way that a pulsating output is obtained from h bridge output. An inverter is a circuit that converts direct current dc to alternating current ac a pwm inverter is a type of circuit that uses modified square waves to simulate the effects of alternating current ac which is suitable for powering most of your household appliances i say most of because there generally exist two types of inverters the first type is the so called a modified square wave. 1 dc to dc converter using push pull topolgy which converts 12 volt dc from battery to 311v dc which is peak voltage of 220 volt ac sine wave. In this article we carry on the design a little ahead and learn how it can be enhanced into a pure sine wave inverter circuit using a couple of additional ics 555 along with the existing ic 4047.
