Part Number: TIDA-00961
Hi, i want to ask about the difference between HS_Gate (EPWM2, 3 for GaN switching) and ACTIVE_PWM_duplicate (EPWM4).
According to both schematic and CCS code,
some circuits or code for ZCS are only related to ACTIVE_PWM (EPWM4) such as initCmpssZvs() and PWMISR().
However, the GaN switches are actived by EPWM2&3 which are not synchronized with the ZCD_Comp, ZCD_OUTPUT as i think.
(In my opinion, in the code, zero crossing of inductor currents do not affect in EPWM for GaN switches)
So I wonder what actually Active PWM stands for. Was the 'Active PWM' intended to operate the GaN switch?
Thanks.
