Initialization of Three phase field effect transistor (33937A) using MBD for MPC5744P

Hello All

 

I am trying to initialize the Three phase field effect transistor (33937A) using MBD for MPC5744

I am using the Example provided as : PMSM_ClosedLoop_mpc5744P (Snapshot 2)

 

For the steps 6a – 6f (snapshot 3)

 

Going in t2_init block (Snapshot 1) -> It says that Highside Off and Lowside ON -> but when I see in scope, both the sides are OFF.

Why is this happening?

Could you please explain how to achieve 6a – 6f (with PWMA inveted), because when I keep PWM value as 0, both sides are low and when I keep PWM value as 1, both sides are high.

Snapshot 2

 

Snapshot 3

 

 

Kind Regards
