Hello!
i am working with 3 level Modular Multilevel converter. For PWM generation i am using TMS320F28335 controller board. the PWM signals 1A,1B and 2A,2B are applied to upper arm of Phase A and PWM signals 3A,3B and 4A,4B are applied to lower arm of phase A having phase shift of 90 degree between PWM signals. Now i want to apply PWM signals to Phase B and Phase C. and we know that the phase angle difference between phase A,B and C is 120 degree. kindly help how i have to give pwm signals to phase B and C? i have attached the line diagram of modular multilevel converter
