Want to try PSIM? - hubs.ly/H0f9wCC0 Why is PSIM preferred for Power Electronics simulation? - hubs.ly/H0f9wFX0 Why you should use PSIM for device level simulations - hubs.ly/H0f9wDk0
Hi Albert, Will PSIM able to perform failure analysis of the power electronics such as (diode, mosfet and capacitor)? For example, when a MOSFET exceed its drain current rating during power converter operation. The MOSFETs drain to source junction will be permanently shorted. May I know, will PSIM able to perform behaviour of this MOSFET failure? Thanks. Will be waiting for your reply.
Hi John, Accurately modelling a device failure is almost impossible. A MOSFET exposed to over current is likely to act as a fuse which may cause it to fail to a dead short or fail as an open circuit, which event will happen? Well that depends on thermal characteristics and physical device properties. Exposing a MOSFET to an overvoltage may or may not cause failure as there is usually a zener diode that can clip the overvoltage, but how much energy it can dissipate before failing is also a complex modelling task. With PSIM you can artificially open circuit or short circuit devices to see the impact on your design which will allow you to devise algorithms to sense these problems.
no the full trial license will come with the spice blocks. Make sure you are using the latest trial. Also check your library settings. Options->settings.. then go to the advanced tab and make sure the "SPICE" tick box is checked.

Thanks for your explanation.

How to solve this problem?
Hi Albert,
I am using the trial PSIM at the moment and I can not see SPICE directive, is it bcs I am not using the full version?
