Herkese merhaba arkadaşlar. https://www.infineon.com/dgdl/AP1609710_different_PWM_for_three_phase_ACIM.pdf?fileId=db3a304412b407950112b40a1bf20453 linkteki akış diyagramı ve spwm notlarını baz alarak avr de vfd yapmak istiyorum. Komutları oluşturdum. Yalnız çıkış PWM leri saçma bir şekilde değişiyor. Komutlar ekte
