Hello,
I design a phse shift full bridge in open Loop mode (without the digital filter). First i generated the PWM-signals like the conventional control of the phase shift full bridge (see Phase shifted Full Bridge Example in the ucd3138 data sheet). That worked great with the "Phase Trigger" command between DPWM0 and DPWM1:).
In my new Control of the DPWMs i want to have that firstly the conventional control of the phase shift full. In my configuration ist DPWM0 the Master and DPWM1 is the slave. That means the setting of the duty cycle will be realised with the shift of the Slave DPWM (in my configuration DPWM1).
After per example 100 periode the PWM generation have to be modified (Per example only the frequency of DPWM1 will be doubled) . After this modification the conventional control have to be released.
Can anybody give me some advice?
Thanks a lot for all your help and time,
Hamda Baatout
