Generating Push-PULL PWM signals using CCU8

[#1]

Hello,

I would like to generate two Inverleaving (PUSHPULL) PWM signals with same duty cycle.
how can i achieve using PWM CCU8?

see attached picture of waveform.

Hi,

I would suggest that you check PWM_CCU8_EXAMPLE_XMC45. There you already have something that is very close to your application.

Hi,

I believe you could achieve interleave PWMs by below methods:-

1. Setting CCU80/CCU81 as Edge Aligned, Asymmetric PWM
CCU80 -> CR1=0, CR2= Duty
CCU81 -> CR1=T/2, CR2 = T/2 + Duty

2. Using Phase Shift Control method
Here, you would use CR2 of CCU80 to control the desired phase shift (180 deg) of CCU81 (w.r.t. CCU80).

Please do mention which of the above 2 works for you.

PS: I am not mentioning the 3rd method here, as even though you would achieve the 180 phase shift but the passive state would also be 'High' for one PWM.
