Hi!
We are trying to simulate a motor driver circuit in TINA TI software. The circuit has UCC21521 motor driver, connected to a hex bridge MOSFET (IXT_96N15P,NMOS) configuration to drive a three phase BLDC motor. We generated PWM signals that will be input to the motor driver using PWL. The driver alone and the MOSFET alone work fine. But when connected to the motor load (as an LR circuit), we are getting convergence error issues. We tried changing convergence parameters like shunt conductance to 100m, which did not sole the error. The relevant pictures are attached herewith.
Please let us know how to resolve this issue.
Thanks and regards,
Sriya.
