    Hopefully someone with a little more experience using TINA can assist me...

    I am driving a transistor via a resistor with a squarewave voltage source.
    I am able, using the power meter tool to measure instantaneous power dissipated in the transistor (it has a resistive-inductive load with freewheeling diode) when doing a transient analysis. By approximating & doing integrals (by hand) I can estimate average dissipation.

    What I would like to do is just plot this average power dissipated by the transistor (i.e. switching & conduction losses) against the frequency of the switching i.e. varying the squarewave source frequency.

    If anyone has any idea how to do this in TINA, please let me know. I think in Orcad it would have been a matter of running an AC sweep and having a voltage & current probe and customising the graph to display =Voltage*Current on the graph.... but the uni has changed to TINA this year.... so far I like it but of course am having to relearn some things.
