PIC sine-wave inverters circuit and software, here:

Hi,
i made my own sine-wave inverter with PIC16F876A,
here is a circuit and source code (for CCS PCWH):

The hex file is from post no #758. the schematic was re uploaded so many times with corrections later. It is important that you read the thread from the beginning, otherwise it will be very difficult for you to finishthe file was deleted,
Hi kiebow,Hello guys i build this inverter and its work fine but i still don't know why the wave form has a small dead time between the first half cycle and the second
const long sine_wave[32] = {8,32,70,122,185,256,334,416,497,575,646,709,761,799,823,831,823,799,761,709,646,575,497,416,334,256,185,122,70,32,8,0};
mr pic gak, why the look up table not complet? i can only see 15 duty cycle instead of 32.
i have already replied to a similar question somwhere in the previous pagesDoes anyone know how to modify the scheme to achieve capacity of at least 1000 watts. As such, the scheme is barely able to produce 400 watts.
hello everyone, i build this inverter and it works fine but when ever in power it on it only come on for 5s then goes off again, i was thinking that my load sensing transformer was not properly wind but i am getting about 3v when i power with 100watts load and i can see about 2.6v at curr h/l that is pin 4 of my pic,and i power my board with 5v through out and help please?
Hi fickle,
Yes, you can use TMS320f28335 for generating a three phase sine wave PWM signal.
This DSC device contains up to 6 enhanced PWM modules, suitable to controlling a full-bridge (with 6-transistors) inverter.
Output voltage value depends only on transformer ratio and pwm signal.

I think this project in the following link is good enough for you https://ww1.microchip.com/downloads/en/AppNotes/01279B.pdfhi Ani
I wants to generate twin PWM outputs for half bridge inverter and twin PWM outputs for Push Pull DC-DC converter, it's means minimum 4 PWM outputs from a single microcontroller but I don't know how do I do.
Can you help me?
