Hello I never succed with PIC programing, so I've assembled a schematic of a simple version pwm sine inverter. I allready have few SG3524 The oscillation frequency of the SG3524 in my schematic are 2.36 khz I can even use one of my big standard EI silicon steel transformer for the output. Anyones can look at my schematic and tell me if it would work ok ? Here is the link to my schematic image: Thank you Bye Gaetan
