    Query related to Thermal Transient analysis

    indu.bala

      Hii Sir,

      i want to perform transient analysis of the Low side Driver e.g. BTS3256D which has power 5W and is switching every 200 micro-seconds and the switching characteristics are a follows-

      Case 1- 0-128 micro second

                 Power = 0.09 W


      Case 2 - 128 - 200 micro second

                   Power = 0 W

      but on setting these conditions for a total transient period of 400 micro seconds I am getting a constant temperature to be 30 deg celsius. It remains unchanged for the total time duration. Kindly help me to perform the transient of this component.

            Hyperlynx thermal  doesn't support to run transient thermal analysis.Y should use  Flotherm solution for transient analyss
