Hello,
I am designing a pure sine wave innverter and am using IR2110 as a driver for the H-bridge. On protues however only IR2112 is available so i used it. I managed to get all the connections in a correct way with a good value for the bootstrap capacitor. However i am always getting a distorted signal on the output of the h-bridge(pic is below). I changed my spwm code and still the same. I am using pic16f877A with 32 values for the sine string.The generated spwm freq. is 16kHz. The clock frequency of the uC is 16MHZ Any ideas why this could happen?
