I have made a SPWM Sine wave inverter. I am using the idea from the following blog Generation of sine wave using SPWM in PIC16F684. I am using PIC 16F684 at 16MHz frequency. I am using mikroC compiler. My DC Bus voltage is 320V DC regulated. My problem is i am getting the same DC voltage at output. My output is 320V ac sine wave. if i connect a fan or any inductive load it will work smooth but voltage is very high. I change the duty cycle to different values but not get a good result. How can i reduce the output to 230V AC?..Is this a hardware or software problem?.i attached my inverter idea. Plz help me...
