I am studying on PIC Reference UPS design manual
It explained briefly on the sine wave generation scheme. Reading the program, I understand that it will start putting 0 on the PWM as duty cycle first. Then next reference value is looked up from the table, compare with the actual singal read from output via A/D converter from which a new PWM value will be calculated.
I am looking for a detailed explanation on such kind of singe wave generation algorithm using a micro controller like PIC.
All I need, I think, is the A/D converter specification, PWM specification and the instruction of the controller to determine the values in look up table, calculate the coefficients for compensation, and some scheme for DC offset correction.
What else more???
Could anybody please give me some links where I could find such kind of detailed information??
A little more detail than this with less complex application will be better.
I only need the sine wave generation part.
Thanks
