Ok, so the problem is that PSim trail version does not allow you to have more than 1 input and 1 output while yuou perform a co simulation with simulink. The problem is enhaced further by the fact that only 6000 data points can be stored with the trial version. Here is the solution ...
OptiMOS MOSFET is Infineon's latest generation N-channel power MOSFETs in 200V and 250V that is optimized specially for dc-dc conversion. It is trademark registered by Infineon N-Channel Power MOSFETs that are class leading power MOSFETs for highest power density and energy efficient solutions. Ultra low gate and output charges together with lowest on state resistance in small footprint packages. They have superior reverse recovery behaviour...
