Power dissipation readout in schematic


I made a LIP converter in qspice and i would like to see the amount of power that is dissipated in the component. In ltspice you use the alt+click function for that. Is there something like that in qspice ?

Add the SPICE directive

.options savepowers=1

and resimulate. Then plot it with Ctrl+Left mouse click.

It isn’t enabled on by default because it bulks up the size of the waveform data file. Also, it add some compute overhead. That’s because it’s not plotting power flow into the component but the actual thermal dissipation. The device currents are separated out between conductive(loss generating) currents and displacement currents(no energy loss).
