Dear Sir ,
we are developing controller based on 28376S C2000 chip , and require to symeteric PWM with complementary signals with deadband.
for that purpose i have used signals A,B of ePWM1 ( i have looked on some example related to PWM) . but the main configuration is
1.PWM in Up Down mode ( Symmetric )
2.High Resoultion mode is enable
3.dead band is endable to generate complementary signlas based on A
the main issue i see is that the complementary signal is not high resoultion
i have Set value to CMPA and CMPAHR (PRD =360 , CMPA=340 , CMPHAR=30*256 +0x80 , ePWM CLK = 100Mhz )
and i have looked on ePWM1A and ePWM1B , indeed ePWM1B is complementary of A , but it doesnt iclude the high resoultion part (by the way no DB dealy was added)
is it possiable to generate complementary high resoultion PWM signlas with deadban enable ?
(by the way setting HRCNFG.SELOUTB to 1 , allow to generate high resoultion complementary signals ... but without deadband)
