The post details comprehensively regarding how to build a pure sinewave inverter circuit using microcontroller circuit with PIC16F72
The following image shows the complete circuit diagram of the sinewave inverter, the images are divided into two in order to fit inside the page, please join them together after printing the two images.
The following image shows the built prototype which tested using a 1200 watt load successfully
The close up of the mother board of the proposed sinewave inverter using PIC16F72 can be witnessed in the following image
This picture shows the PCB track layout for the proposed inverter design.
Hex files and PIC code along with PCB designs of this pure sine wave inverter circuit using PIC16F72 can be downloaded from the above shown links,.........Hope this helps!!
Your schematic does not match with the firmware you linked in the article. One example in your schematic uses a center-tap transformer. But the firmware uses a full bridge transformer that is drive by a H-bridge driver circuit.
how do I get the circuit
Hello, I want the design of DSP based true sine wave circuit design and PCB layout with programming files , let me know if available with you.
Hi BRaj, sorry it is not available to me right now…
can increase the output power of an inverter
yes, by increasing the transformer, MOSFET and battery power ratings
Thank you for your reply
Bro send link for pic 16 F 72
It is given in the article; you can download them.
yes please send it to me also…
let me try it….
This article is very helpful!
Thank you Aron, and Glad you found the post helpful!
