How to make a PWM master that vary from 1 to 90%, steps of 1. The second PWM is 50% duty cycle and must have the same frequency of PWM master and the third is complementary and same as second. PWM master have to phase shift relation to second and third.

One TIM

Use PWM Mode 1 on CCR1, Sweep the CCR1 for CH1 to change the duty

Use PWM Mode 1 on CCR2 = (ARR+1)/2 for 50/50

Use PWM Mode 2 on CCR3 = (ARR+1)/2 for 50/50 anti-phase

TIMx->CCR1 = ((TIMx->ARR + 1) * percent) / 100;
